Seems alot of ppl are having these issues, this past friday with the bad storm the northeast got i was driving to boston, about 45 min in to the drive in the worst weather it started to buck, at first wasnt to hard but got worse and worse. I parked the car all weekend, cant drive in boston on St. Patties day, so on the ride home it didnt do it, i drove it pretty hard i was hitting 90 but it didnt feel right at speed wasnt smooth almost felt like it had a slight shake at 3600rpm. the engine seems to a hace tick but i cant remember if it was doing it before and i dont know if its bad. Ive ahd the car for 3 months and when i bought it a lot of things were done, also i have no lights either any other thoughts would be appreciated.

Ohh would buck in any gear.

Nice find on the ross tech measuring blocks!

 

+1 on the coils, then again you just might need some more cooling for you car (fmic)

 

I just threw a similar CEL yesterday. Turns out I have one or more misfires,

Cyl 1 misfire
large Evap leak

Its either the Coilpacks or the Spark Plugs. In my case, Im getting the plugs replaced, then switching the coilpacks to see which one, if any are bad.

 

Sorry for the delay someone backed into the front of my car and it's been at the body shop for a while. I've been able to pull more codes from it and it looks like 2 and 3 are indeed bad, spark plug or coil I'm not sure yet, still haven't had time to play with it yet been busy with midterms I'm hoping I'll have time this weekend to finally work this issue out.

 

It takes litteraly 10 minutes to remove and replace the plugs. Find the tools and find the time asap because misfires are bad for your engine.
