soo yesterday i was driving my car on the freeway tried to speed up to pass a car up. when i hit 70 mph my car kinda like bogged and slowed down. i tried it again and same thing. i had a bald tire in the rear right soo i changed it. and still same thing. when i hit 70 mph my low traction light goes on and slows me down. PLEASSEEEE HELP anybody had this problem before? any idea what it mite be? thanks guys would be appreciated.

Has it always done this or did you just get the car and it has never gone above 70?

Sounds like a good thing! 70mph is fast enough lol.

On a serious note. Did you have it tuned recently or anything?

Do you have a handheld tuner? Maybe someone you know grabbed it and modified the tune so it's got a 70mph speed limiter on it now.

saucymaro

Haha 70 mph fast enought. Thats what my mom said.
But mmm no I didnt have it tuned maybe previous owner but ive has,a for a few months now and it just started doing this. But when I take traction control off it passes 70????

Maybe a bad unit

I'm with the other guys in asking, "has anyone touched the tune at anytime for any reason?" I don't see why it would do that for no reason, and only at 70mph if the limiter wasn't messed with.

scan the car. im sure theirs a stored code if the tcs is shot.

saucymaro

I scanned it amd the mass.airflow sensor poped up. U guys think that might ne the reason?

will the car rev out all the way in 1st and second gear?

Yes, this sounds like it. The TCS is a red herring and a separate issue.

- The bogging when you hit the accelerator is classic dirty or bad MAF. Exactly what code were you getting?

- The traction control system doesn't work at those speeds, so the low trac light it is telling you that the ABS/TCS system is detecting a wheel slip. This could be a number of issues from a tire mismatch to a sticking brake to a bad wheel sensor. What are the sizes and types of your four tires?

My car is auto and wen I step on it it bogs also. And my two back tires are 275/45/17 but they are diff brand? My two front are 235/50/17 same brand. Will the diff tire brands cause that? Thanks for the help guys

I'd clean the MAF first thing and see if that makes a difference, if no try finding a friend or another MAF you can borrow for testing purposes, if no change, I'd look deeper into tire sizes and such.

One step at a time. Resolve the MAF issue and go from there. I was thinking along the lines of fuel delivery or an exhaust restriction but you've got that code, so deal with that first...

saucymaro

Alright cool thanks guys,my friends dad said he has an extra maf soo im guna try that tomoro hopefully if I have time thanks again. Ill let u guys know what happens

What was the exact MAF code you were getting? Depending on the code, all the MAF cleaner in the world may not resolve it.

This happened to two members on here with two different solutions. Both had your problem. The one was the throttle body was getting caught where it wouldnt open and he found where the cable was getting caught. The other was he just needed a new maf.

sounds like your mom had someone do this

I was thinking the same thing.....maybe mom put a governor on it....

Have you gone on any extended vacations away from your car lately?
