DOBBS FERRY,

ok guys got a question. I'm working on a 90 eclipse, G4CS, FP green, 850's, AEM, 272's, the whole show. It's kind of a long story, but basically, the car never drove after being built 5 years ago. It ran a few times while trying to get tuned, but life got in the way as it tends to do 
. We got back into the car a couple months ago. It wasn't even starting. Put the 850's in..started and ran very well. But once it got to 180* it would shut down, and not restart until it got back down in temp's like 80-90*. But that's not the problem we're having at the moment. The more troubling part is that apparently in cyl.s 1-4, the fuel is washing all the carbon off the ports and into the exhaust system, leaking from the flange's and the such. We pulled the manifold off and it's deff. only out of 1 and 4. So I'm thinking a weak coil pack? I'm not an AEM man so I'm no help other than the fact that I'm a DSM Fanatic, and Pro mechanic for 12 years. My friend doesn't have the ability to go Link right now, so Thats out. there were other problems previously, but the car ran. Trying to figure what direction to go. I want to replace the coils just to see if that helps? Any real info would help greatly...the weather here in NY is going to start warming up in a few weeks, and the track is calling. Thanks, any help is appreciated!!
And By washing the carbon off the ports, I mean washing the carbon off the exhaust ports.
