jmf300

dude it so weird. the car hesitates when shifting from first to second under hard acceleration. and at times jerks a little when accelerating.

we have changed the following and problem still persist.
spark plugs
coil packs
wires
trac ecu
MAF

and still nothing. any ideas?

thanks

have you tested your tps.. if tps out of range it will do exactly what you have described ..

jmf300

no but will do, i will try it tonight and let you know. We also haven't had a CEL at all and the car still does it. any ideas?

I will post a follow up once we change the tps tonight

jmf300

hey ed i changed the entire throttle body assembly with the 3 sensors and nothing, same jerking on any gear when accelerating past 3k. could this be fuel injectors? there is no leak but it feels like the car is holding back. it also feels very rough when you start pressing down on the pedal to accelerate

jmf300

just wanted to follow up and see if anyone knew something about this issue, or anything else to try.
thanks

What was the issue?

jmf300

my boys transmission seems to be the issue. the only left that we had not changed was the ecu, so we did that. once we finished the ecu change we ran the car and continued to do the same hesitation. we are now looking for the transmission to change. he checked the entire car and everything else checks out great.
