Starting problem??? Turns over too much
Hi, I'm new!!
I just bought a 87 GN. When it's started, it turns over several times before it fires. When it does fire, it's very rich. Why does it do this?? Does the superchip have anything to do with this?? Any suggestions from you experts would be greatly appreciated. THANKS!!!

yea get rid of that superchip crap and get one from guys that accually know their the GN's and know what work. Also the GN's are low compresson engines to begin with so it will take a few cranks to get them going. The reason they are rich is because the car is in open loop mode. The car runs at a preditermid mixture and ignores the o2 sensor untill it is warmed up enough to use.

car has to turn over long time before it starts
Well ... your chip is fine, but your injectors are either dirty or warped. I've had this problem with my car and had to replace the injectors. After you shut the car off there is fuel pressure that has to remain in the fuel lines and fuel rail for the next start up. If the injectors are bad this fuel drips from the injectors and puddles in the intake manifold. So when you go to start your car again the pressure has to build up while turning it over. So then it gets fresh fuel from the injectors and also the puddled fuel in the manifold causing it to run rich for a while untill all puddled fuel is used up. A set of Tomco rotary disk injectors will permanently solve this problem as the bosch injectors will warp with heat. This has happened to me twice !!!!!!!!!!!!!! until I got wise and went with the Tomco's. (I drive lots!) I also run a street leathal chip. I like it alot.
