I got a 97 t-bird with a ramdon 3&4 cly misfire. Changed plugs & wires, & coil pack. Still no fix. Did some looking on alldata and it pointed me in the direction of maf sencor so I changed it and it seemed to maked the problem worse. I did compression check, fuel pressure check they are fine. Ive checked the egr & the egr sencor and those are fine too. After the car runs for a long period of time the miss increases at idle. When doing this you can shut the car off and restart n the miss is gone. It can be gone from 10sec-10min then starts all over again.
have the same problem?
