89 corolla dieseling

[Phatstud]

every now and then my car starts dieseling. either sitting at idle or while i'm driving. and then every now and then when i turn off the ignition, it'll do it for about 10 secs or so. like it doesnt want to turn off, diesling/sputtering.

anyone know what i should check for? i've changed the fuel filter about 3 wks ago. changed the plugs, wires, cap about 7 months ago.

someone suggested the idle speed adjustment? then exhaust issues, leak/clogged cat?

i'm not sure how to check either one of those so...

i'm trying to tighten the throttle wire here...



but for some reason i'm not able to. i'm able to pull on it and bring the piece higher up.

is there a way for me to pull the wire up into it and tighten that?

sir, too much carbon deposits inside the engine can cause dieseling. but 1st, try having your engine's timing checked. dieseling is normally caused by an over advanced ignition timing. look for a mechanic who's got an accurate timing light.

dieseling is a potentially serious problem so don't let your engine run like that for too long. it is mainly caused by too much internal heat and that condition could blow a hole right through your pistons.

I have an 89 SR5 that does the same thing, and mine does it because of the fuel octane. If I use 89 or higher it stops it. I usually use an octane boost product, cuz its cheaper than the extra 20 cents per gallon. Anyway, it never hurts to try something like that before doing major repairs!
