1990 cadillac deville 4.5 multiport has a miss

Question From cdwdaddy7 on 1990 cadillac deville 4.5 multiport has a miss

i just bought it, it hadnt been started for about a year but ran fine when i started it. it says run premium but im cheap and used 87. drove it for about 3 days and now its missing at idle and thoughout driving. plugs and wires are fine. cleaned the throttle body. all injectors are fine, replaced dry rotted vacuum lines. plugs are sooty

Response From Hammer Time

it says run premium but im cheap and used 87.

That was real smart. Make sure you use that same philosophy when you buy the new pistons that get melted from that fuel.

Response From Tom Greenleaf

Ditto and been thinking on this car. Did some on a 1992 always cared for. This having set for a year matters totally. First WHY and then how left, indoors garaged or out in the elements?


Fuel would settle and oil would settle to sump that fast - one year and does in brand new cars! Ethanol in the fuel would be on the bottom and oil dry in engine up high. By two years outdoors without antics to store it they usually seize up or need lots of help for running again before even the first crank attempt.


Then you go cheap on octane which is an knock rating not a quality rating and this engine should (who knows now?) adjust itself to the lesser now and then but first time out wasn't such a great idea.


Just how did you determine plugs and wires were OK at all and with dry rotted vacuum lines doesn't seem like this was some cream puff and needed total attention to details before even trying to run it,

Response From cdwdaddy7

and i drove it about 150 miles or a few more before it started the miss

Response From Hammer Time

all injectors are fine,

How, exactly, did you determine that.

Response From cdwdaddy7

i used a stethescope and all were clicking. when i was working on it the other day i took it for a test drive and when i got back my brother had found a hose laying where the car was parked and it doesnt seem to go to the car and i cant find a good diagram to make sure. its a 3/4" hose thats 4" long with an elbow thats an 1" 1/2" long

Response From Hammer Time

The stethoscope trick does not tell you that the injector is not varnished up and plugged.

Response From cdwdaddy7 Top Rated Answer

the miss is most noticable at low range gas pedal. like when your barely giving it gas but when you lay down on it it goes with you. has no power out of the hole. can i just pull the injectors and clean them and put them back in with no harm done? i know they are working and i do wonder if maybe they are clogged. you can hear noise inside the muffler while its running, almost like backfiring inside it

Response From Hammer Time

How do you propose to do that. The varnish is inside the injector

Response From cdwdaddy7

well how do i tell if any are clogged?

Response From Hammer Time

It's not exactly a simple thing to do. You have to perform an injector balance test that requires a very expensive scan tool so the chances of you doing it correctly is very slim.

Response From cdwdaddy7

can I just take them all off and clean them myself?

Response From Hammer Time

No, the dirt is on the inside, not the outside.

Response From cdwdaddy7

so the only way to clean them is to take them and have them cleaned?

Response From Hammer Time

They have machines that clean them off the car or there is a pressure cleaning method on the car that works sometimes.

You really need to have it diagnosed properly to see if you even have an injector issue. If you have an issue with one injector, I would just replace it.

Response From kev2

some thoughts-
the octane would NOT change the quality (cleanliness) of the fuel, varnish as likely with one as the other... NOT saying there are no issues using the wrong fuel.

did you check for codes? to easy to ignore
did you check fuel pressure? a basic test
check for vacuum leaks? again BASICS
new spark plugs- what brand? yeah it matters. REPEAT what brand?
what injector cleaner did you use? some are worthless some I use.
Your concern about converter can be answered with VACUUM gauge...

Response From Hammer Time

Any injector cleaner added to the fuel will be worthless. They are OK as a preventative but will not cure a problem.

Response From cdwdaddy7

if i unplug each injector individually will that tell me if they are getting fuel at least? it will change the way it runs wont it?

Response From Hammer Time

Maybe, maybe not.

A trained tech may be able to see the difference but the ISC is going to compensate the RPM right away.

Response From kev2

jumping around is not a suggested apporach. yoiu have mentioned filter, plugs, injectors, fuel, cat, EGR ,
did you do any BASICS I suggested- @4 replies above?


Anyway why not disable a spark plug to attempt to isolate a misfire?
injectors are a possibility BUT there are easier and cheaper ways to isolate the issue and cylinders...

Response From cdwdaddy7

champion plugs and i did try to isolate the cylinder and all plugs and wires are firing good. no codes cleared the ones i had. one was for freon and the other was from the one time that it stalled. none since

Response From Tom Greenleaf

Question by kev2 back a few posts">>new spark plugs- what brand? yeah it matters. REPEAT what brand?"

OE = AC Delco or you can have problem which is why he asked. May only be my opinion but Champion is great for a lawnmower and about ends there,

T

Response From cdwdaddy7

i like delco to but they are way over priced. ive used champions in everything ive ever had for the last 20 years and never had a foul or fire problem.they are all getting great fire.i pulled injectors and cleaned them internally yesterday. 2 were clogged and one is bad. getting the replacement one this week.

Response From ricksbike

I agree with Tom,never-ever use anything but AC Delco plugs, for some reason all the rest misfire,tried everything,every brand all misfired,I was a cadillac tech for 10 years,did mostly drivability and electrical work.

Response From Hammer Time

i like delco to but they are way over priced. ive used champions in everything ive ever had for the last 20 years

That is a mistake. Every manufacturer engineers their engine to run better on a specific plug. That would be Delco for all GM products, Motorcraft for all ford Products and Champion for Chrysler products. Most Asian vehicles run better on NGK. These are known facts. It DOES matter.

Response From cdwdaddy7

well i got it back up and running today. running much stronger but still has the slight shudder when you are driving and giving it just the right amount of gas. its not a tranny problem at all. when i run the on board it gives no e codes but does give a lot of different p codes. where can i get a list of the codes and how can i clear the p codes? certain that most of them are from it being torn apart and starting up a little rough. could it have anything to do the catylitic conveter or the smog pump?

Response From Tom Greenleaf

Any can be bad and usually price reflects quality but not always. Hey - two truths with a car. Only thing that fires the fuel (gasoline engines) is the spark plug and only things that touch the road are the tires and nothing else much matter if those two items aren't good they are the weak link.


With plugs it comes right down to how lousy some are even packaged for handling before you get them, proper resistance, metal and porcelain issues and how made, one unit of metal or crimped together junk.


Just plain rust resistance of the metal wrecks the whole show later if not changed Spring and Fall like wicked old days.


This car calls for Delco for a reason so even if not the total issue right now it sure could be.


Sample pic of poor quality if it shows..............



^^ Pic was there if it disappears I can't help that,


T

Response From cdwdaddy7

that seems like the only thing left other than the cat converter. i unplugged the tube running to it yesterday and it ran worse so i would assume it isnt that. could it be my egr?

Response From cdwdaddy7

just put new plugs and fuel filter on. put a good plug in each wire and all were getting good fire. filled it up with premium gas and injector cleaner. its not knocking anywhere at all. ive worked on cars for years and consider myself pretty good, and so do others. its got me puzzled.
