Exactly what it states above. I can't figure where it is from. This won't happen when the car is not moving and I rev the engine. I have to be in gear. I will either upshift or downshift and I hear sort of a spark or a click from under the hood. The distrib is hooked up just fine. All of the plugs are in right. I also just put in new grounds and it still does it. The only thing that I can think of is that my timing is really off that bad, which it is pretty bad . Problem with that too. I have never had to adjust the timing on my rex. Where the heck is the harness that I need to jumper? I heard that for my car (a 91 hf) that he harness is on the right under the dash and that there is a grn/white wire and a brn wire in it and that is it. Is this true? Any help is needed

 

Either no one care or no one wants to help. Here is an update. Today I threw codes galor. Code nine is one of them. I've narrowed it down to a nearly blow dist. The rotor wheels in the inside are starting to crack again. I say again because I just had to replace them about a month and a half ago. WHAT IS CAUSING THIS. The only thing that I see wrong is that I am running an HF dist on an Si motor. It is the only thing that I can find around here. Is this against the rules. I could have sworn that they were pretty much the same. Please please help

 

Sounds like it is grounded out somewere. The hf and si dizzy are exactly the same, I ran an hf one on my d16a6 in my 88 hf for years.
