Hi, recently i had to replace the coil and spark plug on the third cylinder but now i am not getting any spark its getting fuel and compression just no fire. i started the car and removed the connectors on one, two and four which reduced the rpm's right away. when i removed the plug on the third cylinder there was no change, but the plug was drenched with fuel. i do not know what to look for next except the connector itself maybe shorted out.

with misfires it is best to have a mechanic do these as you can end up dumping a lot of money and still have problem . he can scan for codes. If you like check for a vacuum leak and check compression on the offending cylinder.

Hello, if I may butt in here,

You could have an ignition coil driver inside the computer that has failed, check for coil pulse to confirm here is a guide that can help you.
