acceleration probs. '90 voyager

acceleration is iffy, if you go down too far on the gas peddle, like to where it will kick down to pass, the motor just falls flat on it's face. but once you let the peddle up alittle it will start to accelerate. i know this isn't much to go by but it pretty much sums it up.

Thanks, Jon

any trouble codes?

you know about the key on-off cycle 3x without starting the engine, then the check engine light will flash you a 2 digit code?

clean out the throttle body? air filter? fuel filter? how long did you have the ignition parts replaced?

hey, i did the on/off thing and got 5 and 5. where would i find the meaning of this code?

and thank you, i had never heard of that before. i hope it gives me an idea what the problem might be

Thank You, Jon

55 is the end of the test. No codes present at this time. Possible plugged cat or fuel pressure problem.
