I haven't done any mods to my car. The last mod I done was a comptech intake around 5 months. I have a hks exhaust and a comptech intake. I pulled the code myself and it was 7 long blips and 2 short ones. And the second code was 7 long ones and 3 short ones. I checked it on the check engine light thread and it said it was a misfire in cylinder 2 and 3. What should I do about my car now? Any advices? Please and thank you.

Pull the plugs and "read" them. see if you can confirm cyls 2 and 3 are burning differently than 1 and 2.

How old are the plugs?

The plugs are about a year old. Maybe a little less. I took it to a shop and they ordered the plugs but I don't think they gapped it correctly. Could that be a problem? Should I pull the spark plugs and see if they look the same?

Before the cel light came on, I noticed that cold startups have been rough and has a weird noise coming out of the exhaust for a couple seconds.

Is it ok to drive with this cel light on??

I can feel the motor shaking when the car is on

I'm conducting a compression test and I followed the diy on here but the car isn't cranking over. Should i plug the fuel fuse back in?

nartnailuj

Compression results are 220, 210, 195, 215

Be patient alot of people work during the day. The compression numbers have some discrepencies. Are you sure you performed the test correctly? Warm engine, injectors unplugged, coil packs out but spark plugs in the other three cylinders your not testing, and gas pedal to the floor so throttle is wide open? Did you pull the plugs and inspect them like Billman suggested? If you can post pictures of each plug and list which cylinder each plug came from. We would love to help you but you need to help us help you
