Alright so I am haveing a problem with my S13. My car is a 1991 240sx coupe with a redtop sr20det swap. It has a T28 turbo pushing 15lbs on it and a reflashed ECU. the problem is when I start the car it idles just fine but then when I start to get on it and about 2,500 rpms the car like bogs and feels like there is no fuel. Sometime after a while the car will start to run normal. I have no idea what the problem is, can someone please help me?

wrong maf, bad maf wiring, maf not plugged in, rom tune is not for your maf, dirty maf

^What they said..Maf.

MAF or your wiring, if you did the swap yourself check over the wiring before jumping to conclusions. a maf is likely the problem but that isnt always the case

Same as above ^^MAFS is dirty, wired wrong, not plugged in all the way or just plain broken. Out of curiosity, has it ever ran properly, or did you just recently finish the swap?

hmm

i think we need about 5 more people to say the exact same thing

The car is actually not mine. It is my friends... He bought the car with the swap in it and all. The car was running fine for over a month, no problems! It only started doing this recently like last week.
