Still have annoying 'hesitation' issues with my 4G94....diagnosed as faulty MAF. So a replacement '605' (after market new) results in severe idling issue. Unstable, stalls and/or hesitates making 4~5K rev takeoffs. Have ordered a s/h OEM MAF to determine if 1) original .... severe flat spot 3~4K rpm, then 2) that 'new' after market MAF .... severe stalling issue and now 3) try a OEM s/h to sort issue???
Running out of options....YES done the plugs, leads, coils, air & fuel filter, fuel pump....even spent $$'s on the dyno!
Diagnosis? Fuel injectors dirty? or faulty MAF......really???
Car does rev to redline when it gets past 4K rpm...so much for injectors.
Would appreciate any further help/advice.
 
Damn, still giving you grief?!

I hope the genuine MAF fixes it for you. I have experienced many many faulty aftermarket units, so I have little faith in them - always optimistic however.

Keep us updated as you can, always helps out

Is that another 's/h OEM MAF' still develops a jerking/hesitation in the 2,000~3,000rpm rev range. Beyond that revs to the red-line.
I'm considering purchasing another s/h OEM MAF replacement before spending $$$'s on a after-market 'pnp/ECU' that does away with the troublesome MAF. Would appreciate any further advice on the subject, as MAF replacement sees like a lottery?
