While idleing, I disconnected each fuel injector just to look for a difference: all made the idle the same amount of roughness. I disconnected the throttle position sensor: the engine stalled and the check engine came on as expected.
The check engine light turned off the next day. But, I had the computer checked and no warning codes appeared, accept for the throttle positioning sensor which I purposely triggered to make sure the check engine light worked.
The engine still loses power while accelerating. If I back off the gas, the engine smoothes out. At 65-70 mph, any hill is an issue. I have to floor the gas just to keep moving and I have to forget using fifth gear.
What should I check next? Thank you for your assistance in advance.
have the same problem?
