well me being the noob i am, was cleaning out my maf on my 305 tpi and broke the little sensor that sticks up(im guessing it was a sensor) anyways went and bought another MAF and every since replacing my car either 1. wont start until a couple of trys, to get it to start i have to press the gas a bit or 2. will stall after sitting with the car in drive for a while say at a drive thru window. any suggestions??? if this has been a previously answered ques link please. Thanks!

 

oops

 

If the replacement Maf was a micro tech or wells, has a circuit board/heatsink chip type, they will run rich at idle and stall when put in drive. they read more Grams per sec at same rpm as bosch making ecm run wider injector pulse (richer)

 

it actually is a bosch off of a 350 tpi motor in a corevtte. they are the same mafs arent they?

 

^ Try resetting the ECM by disconnecting battery for a few minutes, then allow the system to relearn everything. If only the MAF was replaced, and everything else worked fine before-hand, you might have purchased a defective MAF sensor in it's place....

 

yea thats what i was thinking because everything worked fine before. thanks

 

I am not sure of the differance on output of different Maf part numbers. But
have tried different mafs on the same car one after another to see what worked. all idled okay stock 350 stock bua corvette. One style bosch the sensor wire was Horizonal in V type holder the other style was vertical. Age causes more variance peak grams per sec was 187 205 and 255.
