I have tested the FPR good - after removing the vacuum hose pressure went up t0 60 PSI
have not replaced seal on Oil fill tube cap - did not see any smoke coming out of there on my last SMOKE TEST ..
how to test Evap purge valve ?
had the car running for almost half hour now TOO hot for smoke test - SMOKE TEST TOMORROW with engine COLD should be smoke coming out of the exhaust if there is a leak !!
so this is what I observed today after car warm up "
MAF a/c off 3.25 a/c on 4.0 g/s
while car was running disconnected MAF sensor SOMEBODY HELP ME UNDERSTAND THIS
after disconnecting MAF car hesitated a bit almost not noticeable CAR KEPT RUNNING

0280 218 055 986.606.125.02 on new BOSH sensor only difference last 2 numbers 02
