solid check engine light
i am running a 93 civic cx with an h22. everything was running fine till the ignition coil let go so i changed it and now my check engine light is solid . i know that means it is a bad computer but i changed it with 2 other ones and it is the same thing. also i had a sales rep in my store and asked if i wanted to try sea foam to clean out the carbon so i did now the car is like what i just explained, is there anyway that stuff could of screwed up my engine. i searched and read all the posts on the topic but none sounded like my problem. any help please.
and i have reset the computer.

just checking your definition of Solid CEL... solid CEL means you have tried jumpering the service connector and the CEL remains on solid.
changing ECUs should solve this problem, unless you're moving your chip from the first ECU to the next. (points to a bad chip)

check all of your grounds. also, do you have internal or external coil? check the ETM for what wires go where.
did you check your ECM fuse? i've seen those pop, and the car still runs... but it runs like *** with a CEL.

Re: (Mike K)
well it all kinda happened at once the seafoam rep asked me to go start my car to warm it up so i did and it started no problem we waited about 10 minutes for it to warm up than went outside and he proceded to put in the seafoam. than we shut the car off and let it sit for 15 minutes, than i went out to try it and it fired up than died right away and than would not start. i changed the coil and it started right away but with a check engine light an no vtec. now it is real hard to start if it sits for a length of time i have to start it by giving it 1/4 throttle and letting it run for like 5 mins or else if i give it gas it dies.
