So this is a strange one. i have searched and searched for the last 3 days and found nothing. what happens is when i shift into first and start to accelerate the power goes on and off but only for a fraction of a second. this causes the car to buck like crazy. if the clutch is engaged this will stop and i can rev the engine will no problem. this started to happen periodically when i would brake but would not continue like now. no blown fuses, and im on the stock ecu. im really stumped on this one guys.

 

check your grounds, there is one that connects to the exhaust at the flange between the cat and muffler. and more than a few in the engine bay that will play hell with your car if you dont reconnect them.

 

thanks. just changed the exhaust 6 months ago and made sure to reconnect it. this weird this is that i forgot to add is this all started on day when it rained like crazy and has been doing it every since. i have also checked most of my other grounds because of what i read.
anyone else?

 

Check all of the major electrical connections/circuits. Sounds like a bad contact that is being momentarily disconnected by accel/decel G-loads.

 

ok ill do that. when i accel it isnt fast at all. i cant even go 1/4 throttle. im def. gonna check it out. thanks
