96 KA24DE Problem

[new_to_drift]

i swapped a 96 KA24DE into my 89 coupe, and I have a feeling that the person that did my harness/wiring messed up,but i want some help figuring out what else/if there are any other possibilities? My problem is that once my car is warmed up, it is extremely boggy.For example when starting from a stop it will chug for a sec, until it gets into higher revs.And this happens in almost every gear.But when its cold,the car runs normal.I dont get it, the only thing iwas really thinking was that the MAF is wired wrong.But other than that, i have no idea.PLEASE HELP

It sounds like the car is overheating. I had the same problem on my Fiero. In the morning it would start up great, and than after it had been driving and warmed up, it got sluggish. Eventually it died on me at a light and a gas station. I eventually found out that I had a cracked cyclinder head after everything else checked out. The symptoms you're describing sound the same. If I were you, I would have it looked at. To replace the heads cost me $600 for the heads (have to by in pairs), $100 for the headgaskets to replace the old ones, ~$50 in fluids, and another $700 in labor. Since then, the car worked pretty well, but then the car over heated and died again after a trip to Jiffy Lube (Damn grease monkeys!!!!). Anyways, the lesson is, it's probably over heating, have the car looked at, they can run a compression test on the heads for a preliminary, and after that, they can remove the heads and run a carbon test on them. That's how you know if they have a crack. Or it could simply be that the headgaskets are shot and leaking, which will make the heads lose pressure. Have those all checked out, and good luck man.

I had the exact same problem with my frist 240sx. It did it depending on how much gas I would give it though, not what RPM I was at. Anything passed half way after it was warmed up, it would act very sluggish. It turned out to be the spark plug wires, about 8 mechanics later.
