I have a 91 nissan 240 with a swap from a 96 ka24de i have no idea what happened but as i was riding low at around 2500 rpms in 5th gear so 50mph or so the gas stopped reacting then no gas led to a stall after 30 mins or so of being in a parking lto waiting for my ride home car starts runs fine 1 mile later does the same gas quits reacting and stalls finally couldnt get car on at all until i got it home which was a 30 mile trip in which the car was pulled got it on was fine in neutral put in first gear and tried to go and rpms get nasty car stalls ive looked through the forum for hours and seen things about rb25's that have MAF sensor problems with similar things or people with bad fuel filters btu wondering if anyone has heard of a case like mine i mean why would it be good in neutral and as soon as first gear goes in rpms go to s*** and car stalls

sounds like you gotcha self a problem. you say you have an RB25? move this thread to the RB section.

try cranking the car without the maf. it will run but very roughly if the maf is your problem.

Could be anything really i guess, can you rev it fine in neutral?

Do you hear your fuel pump priming?

ok i have the 96ka nto the rb25 and so you guys think prolly maf sensor since the car goes in neutral revs fine then put in gear and the car stalls and dies but obviously car needs air to get engine to move all the drivetrain and s*** so maf would be a start fuel pump i just replaced so what all else could it be?

i guess my question came out wrong so i take off the MAF and start the car like that and it should run somewhat different? and around how much can i get the MAF for?
