got my car back from the tuner today , was running sweet as pie , took it for a drive and after about an hour it started to misfire at just over 3,000rpm , first thoughts was a blown cooler pipe as it was when i floored it but that wasnt the problem.
next thing was must be fouled plugs , replaced them with bcpr6es 's and it made it run a BIT better but the problem still existed.
after that i ran the diagnostics on the ECU and it came back with code 43 which is throttle position circuit.
took the throttle body off and cleaned it and also cleaned the TPS to be sure. that did a bit of f**k all ...
next i unplugged it and that didnt change a thing either.
so now , im wondering what it could be
anyone got suggestions?
