HP 500efi What's the Map & Iac Sensor aftermarket part #'s
#1
I have the 2001 HP500efi Merc motors. What is the aftermarket application or part #s for the Map and IAC sensors. I figure it has to be a GM part. Merc is $200+
Kinda Like the distributor with the 8 pin control module fits 1987 through 1992 Camaro/Firebird Tuned Port Injection V8 engines, as well as 1987 to 1993 full size cars and 1987 to 1995 pick-up trucks etc....
Thanks
Rob

On the IAC, Correct, it's just a GM part, just painted blue . Borg Warner / BWD PN: 21755 . Form there you can cross reference to a brand name you like. BWD = $60 or so. Other aftermarket ones = $35 .
502 and 454 MPI's use the same one.

I haven't needed to replace the MAP sensor yet so I'm unsure of the PN.

Thanks, the Napa # is the same, trying cross over to gm and coming up bunch of diff's #s.
reading the iac on the ddt the one motor is working the iac harder than the other motor.
