95 Tercel twin cam 1.5
 

Hello all. I have been trying to remove the stumble and subsequent continuous misfire. I have to let off the gas to return to running on all 4 again. runs great when cold. New idle valve and new tps I adjusted to .6 volts. I appreciate any time you have to help and thank you all. Tip your waitress. Dave

Possible fuel pump, or filter?

Wrong temperature spark plugs?

I just finished a 5EFE swap into my '92 Tercel and had a similar issue initially. It was almost un-drivable at first, but after closing the plug gap down it cleared right up, and then with a fresh set of plugs it ran like a top.

What have you done so far?
