TII stumbling??? Injector question
1988 TII
20k Fuel filter, pump, fuel system service 3k ago. Just recently the car has started stumbling a bit when cruising and applying the gas pedal slightly. I took it in to shop this week and they had noticed that one of the plugs was fouled(lower front plug). I had just replaced them all about 1000 miles ago. They said they drove it and it was fine. The second I pulled away I knew it wasn't and it started doing it again on the way home. Any ideas? Anyone hear of this problem before? Are injectors from 89-91 interchangeable with 87-88? Any advice would be greatly appreciated....... |
When my 87 TII was stumbling it was because of a bad TPS.
The injectors from the 87-88 have a different ohm rating than the 89-91, I think. A clogged fuel filter would cause some stumbling too. |
Thanks for the info. I will check out the TPS.

Is there anyone you know that could lend you a working TPS to test your car with? When mine was going bad, my mechanic could adjust it and the car would run fine, but after driving a few miles it'd go right back to running like crap.

I don't know anyone that could lend me their TPS.
I did set it 1k ohm at idle and gets 4.75 at WOT with no dead or spike spots. Why would just the lower plug on one rotor foul out? |
Is the wire to that plug okay? If it wasn't firing all the time or getting enough spark, wouldn't it foul out? I would lend you my TPS if I were home (Syracuse) but I am in Iowa for school. I have a mechanic in Syracuse who works on 7s if you're interested.
