Back firing
my car hasnt ran in 4 months, its fixed now but it runs ruff and it was back firing today
and has lack off power, Its a 93, and it ran good b4 it stoped runing, it had a wiring problem, its got a new cam and crank sensors, now,
and the throttle position senser is only 1 year old, i tryed to clean the MAF out but it did not help, and the spark plug wire is not on the O2 senser,
Any ideas

Sounds almost like you have a bad coil .... Check them..

Spark plugs and wires are about a year old, plugs looked good when i pulled them,
Coils are all old, but tested good when i was trying to fix the last problem,
same with my back up coils, but i will retest,
it only doe'* it when the car is cold, but when i first start it up it runs varry good for like 1 min then it starts runing bad, till it warms up, and after it warms up its ok with a big lack of power,
i was thinking its going into limp mode or something, but the cam and crank sensors or new

if it hasn't run in 4 months, then the fuel has probably been sitting there in the tank not being used, and now the car is being run on really old gas. gasoline only has a shelf-life of about 28 days, so it could just be bad gas

'''Sounds like a vacuum leak, '''.... I hope not, i hate vacuum leaks!!!
'''the car is being run on really old gas'''... I ran about a new full tank by now, and it was on E when i got it back.
this car has 85,600 but its stuck on that, The car sat for 8 years B4 i got it from the 1st owner,its a 93,... 85,600 is what it had when i got it, i put maybe 40,000, on it but idk its stuck on that.
So far...
I had to put new brake lines on, thay were all bad from seting in the grass for so long....
I had to swiched out the ICM,
new master cylinder
Put in a used Rack-and-Pinion Steering, {not fun}
2 tune up'* {no O2}
new TPS,cam, crank, and MAF sensors
new EGR
new Cat and muffler
then a bad cam sensor wire
new barring
The tran had no fluid in it when i got it, and has had a small wine at low speeds, but shifts good, still does
TCS and ABS never worked.....
Im gona get some new plugs and wires. and do my best to look for a vacuum leak.
Today when i was swiching the Coils out i snaped one on the nuts on the plate that the ICM sets on..but it still runs,,what is that plate called, its not in my book

You should really fix the odometer. They're very simple.
"Today when i was swiching the Coils out i snaped one on the nuts on the plate that the ICM sets on..but it still runs,,what is that plate called, its not in my book"
Let me think about this.... I have no idea what it'* called, But it'* going to be a junkyard part anyway.

sounds like mine did when the plugs and wires were crappy, and then again when a coil went, and then AGAIN when my MAF sensor crapped out. Although if it was your MAF you should be getting a Check Engine light, at least mine was.
I agree that it sounds like a vacum leak
