Maybe you all can help. I just swapped a redtop in my S13 and the car will barely run. It barely idles at 500rpm and if i give it 5% throttle then it will rev til about 900 rpm or so and then will completely die. After I pull the spark plugs, they are completely fouled from being rich. Completely black after only running for a minute or so. I have two wiring points that Im not completely sure on. Heres what Ive done:
Checked compression and it is good, all cylinders are within 10psi of eachother. I checked to make sure the FPR was working to make sure fuel pressure wasn't going through the roof and it is working properly. I switched MAF's and nothing changed. I keep taking the plugs out and cleaning them so when I try something new, Im starting with fairly fresh plugs. I took the valve cover off and verified that timing is correct.
Im using a Q45 ignitor and using Heavy Throttle's wiring diagram. Is this for sure correct? It almost feels like the coil packs are firing in the wrong order. I also had to hardwire in the two coolant temp. sensors and am not 100% sure I got those right. One is just a single wire and the other is just a two wire which I understand has no polarity.
I have not checked codes yet, but I was wondering if anybody knows why Im running SO RICH that the car wont rev. Also, sometimes when the motor comes to rest it will backfire out the intake and a puff of smoke comes out the intake but only for one puff at the last second before it shuts off.
Please help me, thanks guys.
