Almost like it has hick-ups.

Really odd - it won't happen when I let off the gas...It also shifts just fine - as normal.

But, while I'm accelerating (doesn't really matter at what speed; 20-75 so far) it almost feels like someone's tapping on on the break - very noticeably!

Any ideas what is causing this?

Thanks for the advice!

Read some posts with a similar issue.

Gonna try the 25 second tranny reset tomorrow AM - wish me luck!!!

It could be a bad ignition coil or fuel injector?

In any case, good luck, man!

Thanks for the advice buddy.

I tried the 25 sec reset, but it didn't work

I'll be taking the girl to checkpoint next week for a look.

When is thd last time your plugs have been changed? I had a similar problem that turned out to be a bad plug.

Thanks for the info! I havent changed my plugs, no. So will keep that in mind when I get the car checked out - thanks!

I had an issue like that, turned out to be a battery. Whenever I accelerated the car slams like someone stepped on the brakes. I changed the battery after reading a few posts and that was it. Check the voltage of your battery with the car on and off, should be about 11v off and about 13.5-14 on.

Thanks for the advice. I just Checked the battery and its good to go. so looks like I'm going to get it checked out by South Bay independant next week.

I'll keep you guys posted! Thanks for the responses too!

Could be coils. Pull the code, and if it's coils, it'll tell you which one to change out.

I took it to Checkpoint today and they couldn't find any faults or anything wrong with her when they ran the diagnostics?

I'm back to square one! Very frustrating =/

They said maybe it could be the back pressure in my exhaust system?

Not sure what else to do?
