Motor is SR20DET, z32 MAF, walbro FP, power FC
Symptoms are:
Hard start occasionally. Its the oddest thing. Sometimes it will start right away at the first crank and then other times it will take about 10 crank tries to start. Occasionally, most often it will start on the second crank. This also happens when its hot and cold. Doesnt make a difference.
The car also sputters under heavy throttle at high rpm. It wont hesitate slowly going WOT, but when i downshift to second at 5k RPM and gun it, it sputters like crazy.
Plugs look good.
Wanted an educated guess before i start swapping things out like o-rings, maf, etc etc. Help please :(
