1987, 944s running lean.

[E's(87)944s]

What's up, I have an 87 944s and I'm having a couple of issues. When I bought the car I didn't know it had several different injectors in it... it actually had one injector for a turbo model and one for a 928. The wrong injectors caused a misfire, So I've now replaced them with remanufactured genuine Porsche injectors. However, the car is now running lean. I've put sea-foam through it once to try and clean all of the old gunk out. after I did that I inspected the injector wires and I've replaced them all. the car runs and drives with no problem but it is definitely running lean. I replaced the coil, and the cap and rotor and the wires. The only three things I can think of that would cause the car to run lean are, a.) timing, b.) o2 sensor, and c.) the DME?

What is your fuel pressure reading?

If good, then your coolant temp sensor might be bad. Maybe a bad ECU.

Have a porsche dealer check it out, the can do a diagnostic on it and see whats up..

Vacuum leak?

how are you so sure it is running lean?
do you have a wideband O2 hooked up, or is it failing smog?
