I recently bought my first rx7, its an 88 rx7 GLX with a 13b turbo swap. its been running great up untill this morning. I parked it last night and before i started it up this morning i added some coolant and now it misses and idles around 500 RPM and the miss doesn't change when i rev it. can anyone help me? i didn't do anything other than add coolant. I also checked the plugs and the top two are fine but the bottom ones were dirty and smelled like gas, so i cleaned them and gave it another try and still no improvement.

Any help wiill be much appreciated

 

Sounds like a bad coil....if only two plugs are firing then the two that aren't are not getting the spark. Test the coil, then see if u need a new one. Make sure ou fogure out which it is....trailing or leading first.

 

I checked for spark and there seems to be lots

 

If all the plugs are firing then here wont be any gas on the plugs. Define ons of spark.....is it firing evenly? Consistently?

 

They all jump a 1/4" gap.

I let it sit overnight hoping it was just flooded and when I started it this morning it didn't seem to be missing as bad. Should I just give it a good run and see if it clears up?
