Hey, I've been reading this forum for 2 years now and this is my first post. Im having an issue with my 2006 CTS 3.6 and i cannot find anything on the forum in relation to this issue. So the other day I'm driving on the highway and this camry jumps in my lane with no signal nearly hitting my front right side. I end up tailgating him and he takes off. at this point I'm in sport mode using DSC and i shift down to fourth gear, but when i go to give it WOT the RPM's spike up to around 4-5k almost immediately, but no power is being put down, and I'm not going anywhere. this spike only lasts about a second and the RPM's fall back to around 2k, (still WOT) and nothing is really happening. In first gear WOT does what its supposed to, take off like a bat outta hell and the tires spin for 1/2 second, Second gear WOT no problems either engine is eager to take off, and the same for Third gear.
Ive tested around with this on the highway a few times over the last month, and its the same issue every time. WOT or anything over half pedal yields nothing. She simply won't respond to any hard acceleration on the highway. light acceleration seems normal as far as i can tell.
I don't have any idea what is going on at this point. i don't know if its an air vacuum leak, maybe a clogged filter, engine issue, tranny issue, or an electoral problem.
I love my car more than i love myself and this problem is keeping me up at night knowing i can't put down the power.
Any suggestions?
