Re: fuel injection 200 86

Greg, I'd say by far the easiest and safest way to check it would be to test for a bad injector by process of elimination. First disconnect the plug wire to the #1 cylinder. Does the car run just as bad, but not worse, with the plug disconnected? If so it is almost certainly the injector. This happened in my car. You can do a second check by swapping injectors. Depressurize your fuel system by disconnecting fuel pump fuses and running the car till it sputters or dies. Then loosen the fuel rail enough to get the injectors out. After that, swap the injectors from the #1, and any other cylinder. Does the cylinder with the suspect injector run badly now? If none of these help, I'd check for a proper electrical pulse from the electrical plug going to the #1 injector. I'm not certain how to do this, but if you ask around, this place will answer that question for you very quickly.
