I have had an intermittent issue with my Mk2 Clio Campus Sport ever since I've owned it with it going into limp mode, the engine mangement light coming on, plus the electrical fault light (think its called that) and not being able to rev the car very high, especially on colder days and when its wet. Re-setting the engine mangement light with a cheap code reader fixes the problem and then its fine for a good few weeks.
However, recently the problem has been getting a lot more frequent to the point now where the car is stuck permanently in limp mode. The biggest problem now however is the fact that the car is idling constantly at around 2500-3000 RPM when first started before settling down to around a 2000 RPM idle. I haven't driven it since its been like this but pressing the accelerator whilst stationary, the car is very hesitant and won't rev past 4000 RPM. I've tried taking the throttle body off and carefully cleaning it, which didn't change anything. Also I've tried un-plugging the accelerator pedal itself to see if it was stuck (just trying anything at this point) which also changed nothing. When reading the fault code, it comes up as a P0638 Throttle Actuator Control Range/Performance (Bank 1) if thats any help. Another thing I've noticed, when looking at the live data in the Torque app (only using a cheap OBD code reader), the throttle percent reading is always 20%, no matter if you're pressing the accelerator or not. I've tried this reader in another car and it does read the throttle percent correctly so not sure if this means anything.
I was wondering if anyone knows what would be best to try next? I don't really want to guessing and start spending money are parts that might not fix it.
