Evo V hesitates on acceleration sometimes it runs fine but mostly has this jerky acceleration, Car has Evo 7 motor and a Evo 6.5 TME gearbox also has a 500hp walbro fuel pump and is tuned to run 16.5 psi, checked coil packs with a multimetre but they had the same resistance on both of them. Not sure what the problem is any ideas?

 

Change the plugs and gap to 0.55

 

Try seeing what your tune looks like. Sounds like you need one.
