Hey I am having 2009 Chevy Tahoe. I ran out 9f fuel on highway and had to tow the vehicle. After few start attempts after refuelling the car was fine. After 400 kms engine reduced power, traction control failure, stabilization failure warning appeared with engine check light. After three attempts to reset code via removal of battery terminals. The problem solved. However it reappeared after some time with rough idle. I have got throttle body cleaned the response has improved but it's still rough with an unusual noise. Any guidance
-
Usually the throttle body won't cause the engine to run rough or make any noise. Have you added more gas since the problem happen?
I recommend adding some fuel additive and fill up the gas tank with high octane gas. -
Thanks a lot mate. I have topped up tank with high octane fuel and put two bottles of liqui moly fuel injector cleaner. The drive is intermittent not smooth as before. Regards
