check all your air hoses.

Or is he referring to the 3,000 rpm hesitation? Use the search function of this forum to look for "hesitation" or "3,000 rpm hesitation". If that sounds like your problem, then you will find many suggestions for how to deal with this problem including the use of an improved grounding strap.

ok thank you very much :bigthumb:
it will review it

I forget to me ,my car has a domwpipe gredy 3,5" and line of escape in 3 ", this can have relation? :rolleyes: thanks to answer it will wait for its answer,
excuse my ingles :D

thaks for the informatiom , but the problem of my car is much more than a hesitation , over 3000rpm it does not have power ,almost it does not even walk and with a noise
:(
remember that I change the engine, and I put japanese to him,

my mecanic says to me that is for the engine harnees is bad ?

what do you think?

i have a 97 jap motor that was just put in and it runs just fine, it has nothing to do with the motor being from japan.

ok , it did not have to make modifications?

I saw in post information on differences of the engine japanese and the American,
the differences

but the engine runs with the jap harness?

i think , the problem is the engine harness , in special the in ectors

ouch this thread hurts to read
