car stumbles when the road leans. - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Coming into my small town the road leans a little in a 35mph zone and the car stumbles like it is going dead. It does it everyday no matter how much fuel is in the tank. Has anyone ran into this issue?

Tune, plugs, wires, etc. Could be a number of things. Need more info. Probably just the eforce tune.

tune meaning something to do with the traction control... maybe ...plugs... really? how?

Unreal · 07-31-2013, 09:32 PM

No, computer calibration.

can someone please go into more detail on this please?

Nobody can go into any detail. If your car runs perfect and only does this when it leans just a little, it could be dozens of things causing it. Likely mechanical, might not have to do with the lean, but the slowing down. Pretty rare for the tilt to cause the problem. We don't know from your description.

What has been done to your car, what have you tried to fix it so far. If you don't know what tune is then you need to do a search on this forum, do some reading. Try some of the simple things like a loose plug wire, look for wires touching bare metal.

You might have to datalog your car and send the file to your tuner for him to see what is going on. If it is in the tune, he will fix it.

Are you touching the brakes at that certain location when you get to that location.?
You might have a bad wheel sensor when you apply the brakes.The ECM thinks that 1 of the wheels is locking up and the traction control or abs kicks in.
Kinda a strange problem that you have. Good luck.
Would need more info on what you have done.
If you have headers,check the 02 sensors to see if they are not grounded somewhere.When the car moves abit,it might be grounding out and will cause the car to stumble or stall.

Check for a vacuum leak. DO you have any lines tied to the body that could pull and expose a hole/leak

again like your other two threads this could just be a tune issue. i f your driving the same way every time you come into that spot it may just be a MAF table that needs to be adjusted. sounds like your tune really needs to be looked at with all the little issues you have. did you not have it tuned? or just a CANNED tune?
