Any advice gratefully recieved!
It started with misfiring when the car was cold, engine warning light coming on, hand held codes = O2 sensor fault which cleared. Then the misfire got worse, I cleaned the throttle assembly, & associated breather pipework.
When I refitted the throttle assembly initially there was control, then a backfire and steady revs @ 12000rpm.
The hand held came up with throttle minimum position not found, service required on throttle assembly & no MAF flow.
When I reset the codes there is throttle control, if I switch off the engine its back to 12000 revs.
I have trawled the forum for similar problems there are a few with various solutions, change MAF, O2 sensor.
My fear is that the throttle position sensor has failed when I cleaned the assembly 240 on ebay for a replacement.
The fact it resets could be 2 things (I think)
1 the reset overrides the logic in the ECU and allows a start.
2 the ECU has lost the signal from the TPS & requires to be reloaded, is this possible? maybe a dealer job?
Any advice welcome, thanks in advance.
