Ok so I have narrowed my missfire down to cyl 2. I used the old mechanics trick unplug them while the engine is running and see which one is down. The coil is good and so is the plug as I have good spark. What could be next? Bad injector? is this an easy DIY or should I take it to the shop? New to the TL so please bear with me. PS its a 99 tl

 

How do you know the coil pack is good?

I would just suggest swapping coil pack 2 with one of the others and see if the problem follows the coil pack

 

I did that. i used a brand new one and moved the one that was in 2 to 3 and 1 and it worked fine. it is really frustrating me.

 

maybe a bad injector?

 

I had this happen on my RSX-S too...cyl 3 misfire...so i swapped the OEM coilpacks from 1 and 3 and it never threw out another CEL code.

 

Checking compression now just to be sure I havent dropped a cylinder. crossing my fingers hopefully its a bad injector and not a bad cylinder.

 

Just got done checking compression. I get 170-175 on all cylinders except 2 I get 135. Not what I wanted to see. Any suggestions? Cost to fix and is it worth it?
