1993 JEEP GRAND CHEROKEE LAREDO 4X4

Showing 2 out of 4 Posts | Show 2 Hidden Posts
Question From harleydosia on 1993 JEEP GRAND CHEROKEE LAREDO 4X4

when I stop at a light or put car into gear the rpms will drop all the way down to like 200 from 1000 and shake the car and it feels like it is going to die. this lasts like 2-3 seconds then it goes back to normal(1000) sometimes it will do it 3 or 4 times in a row sometimes once sometimes not at all. only happens when in first gear.

Response From Tom Greenleaf

1,000 isn't normal either. I would start with looking for a vacuum leak,

T

Response From harleydosia

i was told i had a crack in the exhaust manifold. Thzts probably it. how much does that run to be fixed? how long should that be driven like that?

Response From Tom Greenleaf Top Rated Answer

There are some repair products to patch them that I find don't last. Just search out the price of a new one and add an uncertain (to me) amount of time to replace it. If bolts and connection to pipe don't behave it can be labor intensive.

Not really sure that would cause the fairly wild swing in RPMs by itself. It may have burned something that counts or is confusing an o2 sensor - not sure?? An intake manifold or vacuum line leak to it. Intake manifold vacuum is a good measure of the load on the engine and other items are adjusted based on engine load which could cause your symptoms. Intake manifold leaks also don't usually impair the feel or operation when under part or full load/demand on the engine unless they are real bad,

Response From dave284

With a vehicle this old...you are expecting wear, long as the compression readings aren't more than 15% of each other it I would think the rings would be o.k. A vacuum reading would give some insight too. Fouled plugs indicate a over rich fuel mixture....so you could be looking at replacing/rebuilding carb. BTW did you use oil in your compression test?

Response From Tom Greenleaf Top Rated Answer

These had tons of troubles with intake manifold to head sealing and carb problems common. Carbon build up could account for high compression which with high load will knock.

Spray all around carb base and intake manifold for vacuum leaks. Generally when running ok - a good hwy run will clear out carbon build up,

stalling out('73 JEEP)Old Mial Jeep

Question From rsuda on stalling out('73 JEEP)Old Mial Jeep

Hey Guys,I'm having a problem with my mail jeep stalling out.It has a straight 6, carb.,and lousy points.It will idle in park just fine and stall out at times while delivering from box to box and then clear up and run fine.I also noticed if I hop back in the seat and shake the cab it seems like it's missing.I've tried adjusting the idle,fuel mixture,points and timing.I'm loosing my patience.What do think it might be? THANKS!!!!

Response From Tom Greenleaf Top Rated Answer

Some common stuff was a loose carb or intake manifold leaks. The points still have to be right and you can test the distributor's bearings by using a dwell tach and rev the engine. Dwell should not move more than five degrees or it could be the problem. That would be the distributor bearings. Distributors can be rebuilt and new points set exactly by some old time rebuilders. The condenser should go too.

Gray hair can pay off!! T

Response From rsuda

Hey Tom,I used a dwell meter and the distributor bearings are good.I did test for vacuum, and I have a leak.The guage,as soon as I shut the ignition off dropped from 20 to 0,instantly.I figured the guage should have held some pressure.Would a leaky intake,carb.,or vacuum line cause this?THANKS!!!!!

Response From Tom Greenleaf

When you shut down the engine vacuum will about dissapear immediately except for maybe a reservoir ball may hang on a while. I think you have it -- go 4 it, T

1978 Jeep cj5 dies at adle rough running smoke

Showing 2 out of 13 Posts | Show 11 Hidden Posts
Question From Guest on 1978 Jeep cj5 dies at adle rough running smoke

My cj5 has been sitting for a few years - started right up after replacing motor mounts and putting some new body parts on - was running fone for the last few weeks short trips around the block - today suddenly started to run rough, and die at idle. Will start right up if I punp the gas pedal but will not idel and smokes alot when revving- any advice??

Response From Guest

Thanks Guys! - Took the carb back off finished the rebuild including the accellerator pump and cleaned it all out again - checked and adjusted the float level and drop etc - took care of it - running great now - on to the next thing! Appreciate your insight

Response From Tom Greenleaf

Great to hear the good news! Thanks for the feedback on how it worked out,

T

Response From Guest

OK Guys - Took the carb apart and replaced the needle and seat and generally cleaned her up - reinstalled- still running the same - but noticed that if I take off the large vacuum hose that goes from the base of the carb to the valve cover the engin will idle and run smoothly but still smokes. Any advice??

Response From Tom Greenleaf

Needle valve doesn't dictate level of fuel - floats do and must me measured,

T

Response From Hammer Time

What color is the smoke? Blue/gray, black, white?
Any odor to the smoke?
Is the check engine light coming on?

Response From Guest

Smoke is gray/black fills garage and stings the eyes - there is no check engine light or really any electronics on this thing other than the electronic ignition.

Response From Hammer Time

Sorry, didn't notice the year at first.

It sounds like the engine is running way too rich. That would have to be caused by something in the carburetor. You may have gotten a piece of dirt caught in the needle and seat causing it to flood over. You really need some carb knowledge to take that apart though.

Response From Guest

Thanks-

That makes sense- When I took the air cleaner off when it first died there was part of an acorn inside the air filter - not sure how it could have gotten in there there - maybe a squirrel -

Any way to clean it without taking it apart??

Response From Hammer Time

No, the control valve that controls the fuel level is internal and would most likely have to be disassembled to access it.
You can try removing the fuel inlet line and see if the is a removable fitting after it but most aren't designed that way.

Response From Tom Greenleaf Top Rated Answer

To add: 258 six - right? Wild problems with intake manifold and at the age now think sunken floats in carb. Just my 2 cents which lateley has only been worth that

More: Once fouled up plugs must be made to work and eventually replaced or screws up diagnosing it...........

Response From Guest

Yes 258 Six - so rebuilding the carb and replacing the plus is a good place to start??

Response From DanD

Here’s my 2 cents; not worth as much as Tom’s; I’m talking Canadian funds EH. LOL
I agree with Hammer, Tom and your thoughts of having the carb rebuilt; kind of a dead give away with you saying “Smoke is gray/black fills garage and stings the eyes”; there’s nothing like air saturated with hydrocarbons and carbon monoxide. LOL
Hope you get the jeep running properly; there’s nothing like the bottom end torque of those old 258’s.
I had one in a Gremlin back in the seventies; that thing would have the tires still just a smoken coming out of second gear; but then ran out of steam at 70mph. LOL

1972 Jeep CJ6 overheating

Showing 2 out of 2 Posts
Question From gthompson72 on 1972 Jeep CJ6 overheating

Hello, I need some help please. I have a 1972 Jeep CJ6 304 V8. I have replaced the thermostat and water pump and I am still having an overheating issue. It is really weird too, one side (passenger) of the engine gets blazing hot to the touch and the other does not heat up hardly at all....Any ideas what's going on here? Thank you

Response From Tom Greenleaf Top Rated Answer

'72 - Whooo doggie! V8 - that should be an International Harvester engine - maybe. Lot's in the vintage used a "heat" riser on passenger's side exhaust manifolt to shoot hot exhaust from that side, thru intake manifold to driver's side to warm up the engine faster from cold. Might be an external weight and heat sensitive spring you can see. I doulbt that year it was vacuum motor operated - just weight and a clock type spring.

If you see something like that when cold try turning it. It's like a choke plate in there and the stick hard sometimes. It's basically ok to just leave those locked open but it take a bit longer to warm up and might not run as well cold.

Is that was is there on this?

T
