GT86 Poor Starting High Fuel Consumption

Hey there! I had a similar issue with my GT86. Higher fuel consumption and poor starting are classic symptoms. Have you checked the throttle position sensor or given the throttle body a good cleaning? Might be worth investigating the air intake too, just to rule out any blockages.

Thanks for the tip! So, did cleaning the throttle body solve the problem for you? Or did you have to replace the throttle position sensor? How can I check the throttle position sensor? Any advice on how to get to the throttle body? I'm not a mechanic, so I'm a bit nervous about messing things up!

While cleaning the throttle body might help as a temporary fix, in my case, the root cause was indeed the accelerator pedal module. The symptoms kept returning until I replaced it. Considering your novice expertise, I'd strongly suggest taking it to a reputable workshop. They can properly diagnose the issue and replace the module. Messing with the control valve without proper knowledge can lead to bigger problems.

Thanks a bunch for your help! I took your advice and went to a workshop. Turns out, you were right! It was the accelerator pedal module. They replaced it, and the car is running perfectly now. The final repair cost was 205€. Really appreciate the advice!
