AAARRRRGGGGGHHH!!! I hate workin on cages!

Whoever decided cars needed to be complicated machines needs to be F**king shot. I'm working on my tercel today, after it decides to run on only 3 cylinders due to some problem I cant yet identify. so far, I've cleaned the EGR system, replaced plugs, and I'm about to just shoot it.

thus far, I know its the #1 cylinder misfiring, and its REALLY bad, like to the point where I cant even freakin drive the car as it is. not even enough power to move without the engine stalling.

Double check the fireing order and and if you tryed that then check it again.

Its not possible to get the firing order wrong, the plug wires are in a sequence, the plug wire for each cylinder is longer than the one before it, and I havent removed more than one wire at a time from the distributor.

Thanks for the idea though, I'll check it in the morning just to be POSITIVE, I never even THOUGHT of the freakin firing order being wrong.

pull the codes out. do a google search on how to get the diagnostic codes from the dash.

3 basics for any engine:

air
fuel
ignition (spark)

check each of those system for functionality.

Back Marker, problem with that concept, this car is ENTIRELY mechanical, no codes can be pulled from it. besides, its not pulling a check engine light.

the #1 plug was the only one on the other set of plugs to be covered in carbon deposits, so I'm pretty sure thats the misfiring cylinder. its got an old distributor type ignition, I'm going to pull that tomorrow and check it out for anything that could cause misfiring.

a rotor distributor? Oh yeah, just a bad contact is the best case scenero. cheap and easy if thats the case.

That isnt very useful to me. I want to know what the worst case scenario could be, like what kind of problem. sorry if I sound a little unpleasant, I'm just REALLY REALLY REALLY frustrated and ready to kill something.

what year is it? is it fuel injected? have you changed the plug wires already and done a complete maintenance service?

Its an 86 toyota with the 3AC motor. given its got 229K miles on the clock, I'm going to check something VERY obvious, it wont run right at all, so I'm going to try pulling the cat off and checking for obstructions in that.
this wouldnt surprise me, since this issue is one that has gotten worse in a very rapid manner, as though carbon chunks just broke loose from the exhaust manifold and plugged the converter up pretty good. anything is possible you know.

do you have the 4WD or FWD version? 5 or 6spd TR.?
- So the engine fires up? but stalls when engaged into gear? does it idle low? or coughup idle?
- before you replace the Cat, jus un-install the exhaust system and test it to make sure it carbon build-up in the Converter.
dont worry, this problem will get fixed. I dont have too much experienc in Carb engines, but if i can work on DOHC EFI, im sure an 86 tercel couldn't be that hard. Your workin with a SOHC pushrod engine right?

you could think of it this way. some people pay extra to have their cars run on less cylinders.

I'm with ya here man! I haven't been posting on TWF lately for the past 2 weeks because all I've been doing is working on my car!

I have a misfire and backfire up in the engine bay somewhere. I replaced the plugs/wires....still there, then I replaced the fuel filter...still there, then I tested the coil packs...tested ok, so I bought a new pack..moved it around to all 3 locations...still there, I bypassed the EGR valve...still there. I seafoamed the fuel lines...still there, cleaned the throttle body...still there. also have a high idle problem...so I replaced the IAC (Intake Air Control) still there. I replaced the TPS (throttle position sensor)...still there.

I ordered a ICM (ignition control module) since those are prone for going out...I'll have to wait for that to arrive next week. Next I will get a cam position sensor if it doesn't fix the problem. I am just getting so frustrated with the car...it's not my only car for transportation...but it's got 243,800 miles on her, and I'm just trying to keep her alive....I don't think it's anything internal the engine is still so smooth.

my 1994 Pontiac Firebird with a 3.4L V6

I've had the car since it was new...my dad ordered it in 94, then he gave it to me in 99....nothing has really ever gone wrong with the car with this many miles on it except for the normal up keep stuff...brakes, alternators, suspension, battery....etc.
