Hey guys, this is my first post on Zilvia.net! I'm stoked to be a member. But anyways.

I just bought my first 240, and it had been sitting for around 7-8 months. I purchased the car last week and since then i have changed the fuel pump, changed out a injector, installed a new battery, spark plugs, fuel filter, changed the oil, filled up the tank and ran some sea foam through it, and ive driven the car maybe 150 or so miles since the day i bought it. It drove fine up until today.

The ka24de came out of a 1995 s14 and is rebuilt with 80k miles and new OEM pistons and rods. The car fluctuates in idle but not significantly. And when in gear, i press on the gas anywhere from minimal to medium or even 3/4 way down and the car seems to bogg and has a major delay in acceleration.

Any advice would be much appreciated! I'm gonna clean the MAF and IACV tomorrow and see if it doesnt help. Oh also. The exaust is welded all the way back from the header and at the resonator it has a small crack where it leaks. I ordered a new catback exaust today and when it gets here im gonna find a good header to use.
