After getting the tranny in and everything running Im having an issue with the car I cant seem to iron out. Ive tried several little things, and I have a few more ideas but I'd like to get some 3rd party input.
The problem boils down to this: 90% of the time the car idles fine, the other 10% it randombly sputters/misses. When in gear I can drive the car like a grandma and I usually dont see any mis-fire but If i try to put my foot in it the car starts to mis-fire, bad. I did some earlier diagnosis to find out that I think the cylinder 1 (closest to T-belt) is the one that usually doesnt fire if the car is missing. I just pulled the injector off and did a resistance check. I think it settled about 8 ohms but I've been trying to find the info but no luck, so I dont know what its supposed to be. Anyways I'm here for your guys help/input/ideas! Thanks -------------------- 1990 Nissan 300ZX T

Sounds a lot like a boost leak....

The hesitation under load (boost) makes me think spark blowout. I also agree that it could be a large vacuum/boost leak.

Have you checked your cyl #1 spark plug after running the engine to see if its soaked with fuel? I'd check your spark on that cyl also.

Thanks for the input
I measured the other injectors and their resistance is around 3.2-3.5 for all of them and the cylinder one is at near 6-8 ohms like I said earlier. This leads me to believe that when its receiving voltage from the harness that since the resistance is higher that its going to miss (because more pedal = more voltage) if you guys get what im saying Anyone have any auto turbo injectors I can buy/borrow? -------------------- 1990 Nissan 300ZX T
