sr20det idle problem

[supraboi18]

Car idles for a few secs and cuts off.. But when i unplug the MAF(Z32) it idles fine.. but cant go pass 1 or 2 rpm.. but as soon as i plug back the MAF it dies out..I order another MAF and the same thing happens.. HAve anyone ever had this problem before??

what motor is it, what mods do you have, in what year car, and what management do you have.

if your trying to run a z32maf on stock ecu with no piggy back..that would be your problem

Im running the z32 on a blk top sr with a gt28 on a 95s14.. its still have the stock ecu...i think it was piggy back by the SAFC2.. Cause my battery die before and prolly it lose all the memory in the safc2?? How could i tune it back?? cause as soon as i plug in the MAF car dies out...

cool you have an sr in a supra? just kidding..sounds like you need to learn how to tune the safc2 because it definately sounds like your problem lies in there. (i dont think you lose memory when unhooking the battery that would be gay and if that were the case a waste of money i feel) Did you buy the car with these mods? how was it running before the battery situation? you can put a volt meter on the maf witht he key in the "ON" position. The black and white wire should have 12volts and the white wire should have 5volts

2 In 5 Out (AFC Setting) for a Z32 MAFS on a SR20DET IIRC.
