I have a 93 eg civic it has a d16a block with a d16z6 head and the valves are knocking really bad and misfire in cylinders 3 & 4 and I can't figure out what the problem is it has a wire tuck also but I don't think that's the problem I need some help bad

 

P28 ECU?

CEL codes?

Cyls 3 and 4 have spark and fuel?

Have you compression tested the cylinders?

 

They have spark and fuel and compression idk about the ecu and what do you mean cel codes

 

You must give details.

Post the compression numbers, and also click the Codes link in my signature.

What color is spark at 3 and 4, and how do you know the cylinders have fuel?

 

The compressions at around 150 and what link and I'm not around the car to see the color of the spark and I'm pretty sure its getting fuel cuz I smelt fuel in the exhaust

 

If that's all the detail you have, then you'll need to put in more effort to receive help.

If you are mobile, you may not see my signature links. Check using a PC.

 

I can't find the codes link

 

OK thanks for the help man I'll try to get more details

 

it says codes in his signature
