Sorry... I thought I had that in a signature line. It's a '96, 4.0 auto.
I've been getting intermittent problems. Rough idle, low power, can't drive above 40km/h sometimes, popping sounds from the manifold when under load such as climbing a hill, almost sounds like backfiring. Then, it will all go away. I haven't had a problem for 6 weeks, and it came back today. I've done cap, wires, rotor, CPS, TPS, and IAC in the last 6-8 months. There is spark at all cylinders, new air filter, and the fuel filter is one year old. I'm kinda stumped. Oh yeah, no codes!!! I have an OBD II tester, and no check engine light, and no codes. Any ideas??
