Hi just got new maf put in car still runs when is taken out but runs lumpy Please Help

 

Sorry but can you post again but this time so we can understand what you mean.

 

sorry got a mate to post over the phone, right then as far as I understand if you disconect the mass air flow sensor the car should stop running, whitch it did not ,it just kept running lumppy, so I went out got a new maf, fitted that today started the car pulled the plug on the maf sensor and same again keeps running on, the car is very hesitant at say between 3/4/5 thousand revs, and tick over is about 800-1000, tryed the ecu reset no joy? can any one help pleaseill try reseting the ecu for a while longer see if that helps

regards magic

 

so you've fitted the new MAF and done an ECU reset and it runs no better? What year and model Impreza is it?

 

its a 99 reg, t 2000, how long should I reset the ecu for? ok just reset ecu under dash (green wires) made no differance. no codes come up just keeps on running when disconnecting MAF sensor?

 

god help me plz can I have my apexi and tdo5 back plz....

 

your car uses the lambda at tickover, not the maf.
