Re: 93 civic dx hatchback BIG problem HELP!!
first of all you have a valve pan leak from the seals around the spark plug chambers. oil soaked plugs are a giveaway. second they are probably fouled. overheating sounds like a bad water pump to be honest, and they are known to go out, be sure if you replace it to change the timing belt with it. If its sounding like its revving when you stable the rpms say at like 3k, and the needle is bouncing, it is 9 times out of 10 the iacv, could also be a vacuum leak so have someone run a vac test on it. The gas smell from the exhaust means its running rich somewhere, which can be caused by a vacuum leak to be honest with you. It could also explain the stalling and lack of acceleration as well. It will also cause your gas milage to suck royally. So thats what ive got for you i hope some of what ive babbled about is useful, good luck.

oh and just because the injectors have been cleaned doesnt mean they are working properly....i found this out myself. also if you have any check engine lights that would be of big help as well.
