1992 nissan 240sx with sr20det

[briandaley]

Hey I need help with my sr20det. It doesnt run right. It idles fines for a couple seconds and then it starts missing. Then when I give it full throttle it misses a lot but it still drives just has no power. Compression is fine 150-155 all four cylinders. TPS is new. MAF is new. Fuel filter is new. Vacuum is at -20psi. Timing is dead on. I just can't figure it out. Everything I have done has seemes to do some good but I still can't make it better. Any help would be appreciated.
