Car vibrates when I drive with the AC on. I have changed the injector mouth - throttle body two times, but the problem persist.

There is a red break light error permanently shown on the dashboard. Could this be the cause? Thank you.

no the brake light should be scanned for codes as it's an abs issue, like maybe sensor /broken wire etc. your issue of vibration with a/c on may be due to a bad belt and tensioner which recommended replacement is 60,000 mi for both.

Hello Sir,

Thank you for the information to solve the vibration problem in my Honda Accord 2003 EX, 4cyl. I changed the tension belt as you suggested but the problem still persist.

I noticed that whenever I powered the AC and press the break for selection of the gear, the reverse gear does not vibrate at all, but the drive gear vibrates when the power drops abruptly. Please your advise would be appreciated. Thank you

Regards,

Lambosky

this is something that may need to be physically tested. the only thing that I can think of is to check torque converter bolts, motor mounts and axles and wheel bearings for this. it cold be any of those. drive in a circle like right hand and if noise increases may be a wheel bearing on opposite side. same vice versa. other than that i'd have to physically look at it which I can't do
