Hello everyone , any advice for the following codes ?
29e0 mixture control 1 lean
29e1 mixture control 2 lean
29f1 fuel pressure , plausibility
the long term fuel trims are over 25% when the car is cruising at around 2200rpm and they go back to 0-3% when i flat throttle down
the short term fuel trims are +-2 all times
I replaced the Lpfp , the filter and the fuel pressure sensor but nothing changed , should i risk to buy a new Hp fuel pump ?
the interesting part is that the check engine light comes and goes at its own and the car doesnt give any other sign that something isnt right.
the cold start is good,
the car does not stall under pressure and cruises normally
no signs of misfires .
