Any ideas what could be going on? I only use ExxonMobil 93 gas. Gas cap is tight. Never had any braking problem outside of when the ABS VSA light comes on when I'm driving sometimes. It will stay on for a while then it might go off but the engine light is always on. The dealership said something about a bad knock sensor but I don't know cause the tranny seems to be a little jerky now too well a lot jerky sometimes usually when I'm cruising at maybe lets say 45 50 and I hit the gas and the rpm shoots up and the tranny down shifts thats when I feel the most jerk.

 

could be the ABS module gone south. same thing happened on a friend's Jetta.

 

wha kinda car,yr you got?

 

04 Acura TL

 

I have the same Jerkiness, especially when downshifting to second gear, even at like 15 MPH! My engine light was supposedly due to a software issue and air fuel ratio sensor which they replaced, but still have issue. I also get the light flashing on when staying in gear driving on the highway and once in awhile miscellaneous times just driving regular the light will just come on and stay for a couple hours then go away....this needs to be handled!

 

Just came across this thread, I know its kind of late but hope you guys are still checking.
I have a 2003 TL-S and I got the same problem for this past weekend, took it to the dealer first thing monday morning and left the car running with all the warning lights displaying. I refused to leave the service counter until someone came out to the parking lot with me to look at the car.
They then gave me a loaner car and I called Acura/Honda client service as soon as I got to the office. The dealer called me yesterday and told me the problem is with the "Fuel Injectors" and they are going to replace them all and I sould be able to get my car back tomorrow.
Hope this helps!

 

2003TLS? You hijack this thread to 2G TL?

 

But I bet you they are probably using the same fuel injectors.
