HI I have a 95 tbird,4.6 v8 with 36000 miles,about 3 weeks ago the engine
started to miss, sound like "pop" coming from the engine.
when the car is cold works "ok" but after 2 minutes of runing the engine
the problem appears the hotter the engine gets, the worts it gets,
from 500 to 3000 rpms feels like no gas or sparkplug problem, but pass 3000 rpm and the problem is gone.
I changed sparkplugs, fuel filter, cheqed the coils, no check engine ligth
thanks.

cuold it be the coil packs? mine did the same thing

[pugaus1]

I did check the coil packs, acoording to the manual, they should between
13k ohms and 14.0k ohms. when my the car is cold they are 14.0 k, and when the car is hot 14.9k, is that normal, or my coils are bad?

check the wires to see if they arking across from one to another, this could cause a backfire or pop sound. also is the check engine light on?

[pugaus1]

I cheked the wires, I didn't see no arking, I cheked
ohms in the wires, they are in range, I did check the
ohms in fuel injectors they are in range too.
no check engine light.

Pull your codes anyway. Not have the CEL illuminate doesn't mean there aren't codes. Once that is done, if we can't help, post over on the 4.6 board of www.tccoa.com and ask the guru's there.
