Thread: TCC lock up solenoid bad. 98 gp gt

anyone?

transmission?

clogged cat?

its got a brand new magnaflow cat. it presents itself as if it was the transmission shifting from 4th to 3rd and back up. but it doesnt jerk like the tranmission, its more of a lumbering back and forth as if you were feathering the throttle very quickly

it was throwing a lean bank 1 code for the longest time. replaced the pcv valve and the code went away but the problem didnt

Try shorting the positive and negative battery leads.
this will reset the learned PCM tranny settings.

a PCM reflash would do the same thing.

short it out? as in cross them with like a wrench or something?

Disconnecting them first, of course. Then touch 'em together.

disconnect the battery and then touch the cables together? or the battery terminals (which makes no sense)

The leads, not the battery itself.

ok. any ideas about the power loss?

This will reset PCM settings.

Try it and see what happens.

ive reset the pcm about 100 times. and does the evap vent solenoid effect the operation or performance of the motor. because mine is no longer working

if it was stuck open then it probably would.

its stopped working between last night and a month ago.

its a $30 part.

got the power issue solved. the persistent stutter and fluxuation of the rpms is pissing me off

what fixed the power issue?

the rockers were out of order. and it didnt do much for the power. a little but not much. maf and map are both new. it cant be anything in the tranny because it does it in both third and forth, but not second because the rpms are too high. the only thing i think it could be is the ign control mod. i had it tested last year and it came back good. it doesnt have any other issues. no starting issues or anything. never misses, just stutters. i replaced the lim gasket thinking it was a leak. the exhaust man gasket seems to be leaky but i dont think that would cause problems since its EFI
