Hey guys. I finished my s50 swap about a week ago and it's running horribly. It will barely idle; it bonces between 400 and 600 rpms and it's running extremely rich. So rich, that I'm getting a lot of black smoke out of the exhaust at idle. I haven't tried to drive it yet, but it hesitates badly when I touch the gas and then nearly stalls when I let off. Here's the relevant info:
S50 that supposedly ran great when pulled
new 3.5" bosch MAF
pink top injectors
new o2 sensor
new oem fuel pressure regulator
I cleaned the icv and it spins freely
It's obd1 on a 413 ecu with a tune for the MAF and injectors
I also tested the tps sensor and it looks good
I thought that it might be an issue with the tune or injectors, so I swapped the stock 17's and stock(non-ews) ecu in, and that made no difference. I also listened to each of the injectors with a stethoscope and I can hear them all clicking.
I'm running out of ideas. I was thinking that it could be the cam position sensor, but I don't really want to spend $100 just to try it. Any ideas?
