greetings!!!
I own a jeep cherokee sport 1999 4.0 4x4 standard gear with 157k miles. Once i was driving down a hill, when suddenly i noticed that the motor was not compressing, instead it began to gain more acceleration, so i had to finish going down in neutral. when i checked the engine compartment, i noticed that the racing tipe air filter (sorry, i don´t know the name, hope you can understand) that it had instead of the normal air filter, fell off. I put it back on its place, but it is still giving me the problem ever since.
I have already replaced the gas pump, gas filter, cranckshaft position sensor, TPS, IAC valve, ignition coil, and spark plugs.
Now it runs a bit better, but every time i turn on the engine goes directly up to 2k rpm and goes down slowly, if i pass over 2k rpm to shift gear always goes down slowly, and sometimes, when im drivin down a hill, the motor accelerates by itself up to 3k rpm and it won´t slow down, i have to stop and turn it off.
Does somebody thinks the camshaft position sensor could give me this problem?
Has someone already had this problem and fixed it? I would so much apreciate your comments!!! Bless you all
