• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

sometimes when i pull onto the highway, while accelerating the rpms jump up and down until i let off. then its fine. this only happens sometimes. no codes/ses. and when im on the highway or goin like 60-70 the car will bog down but if i let off and get back on it goes like it should. does anyone have anyidea whats going on? i have new plugs/wires probly 3k ago.
 


is it jumping because the tranny is letting go of the motor or is it a running problem...if this has been happening since the plugs id guess you cracked a plug or didnt use dialectric on the wires before putting them on and now you have moisture between the plugs and wires...if not it could also be the coils but that would be a coincidence and id lean toward installation error to start
 
Sounds like a TCC solenoid issue. The TC is locking/unlocking. Try disconnecting BOTH battery cables, touching them together for about 30 seconds, and then leave them off overnight. Then reconnect and take a drive to let everything re-learn and see if this issue clears up.
