Help!!!
 

About 2 weeks ago while sitting at a light, my car started to idle really rough. After the light changed, I started to go and the car hesitated and chugged foward until I got to about 2000rpm. After I got to the next light, the car was running fine like nothing was wrong. A couple days later it did it again, but this time it did it for about 15 min. After that, it didn't do it again for a week. Could my opti be going out. The car only has 63k on it. I changed the o2 about a month ago, and I put new plugs, wires, and a coil in it about a year ago.

may be your opti my car did that when i fouled out a plug in it to

No codes? Other things that could affect that also are the ICM and coolant temp sensor in the water pump. Check the opti harness.

I did have an opti do what you are saying just a few months ago. Sometimes the car drove fine, other times it was bucking like it was trying to die and then would be fine shortly after.

Could be Fuel pump, coil module and yeah opti. Not to say anything but that MSD billet opti is awsome! I've never had an issue in 3yrs.

Sounds like opti to me

Deff an opti or like said above, fuelpump or clogged lines,filter,injectors etc...

Thanks for the help guys! I have some free time this weekend, so I'll check all the fuel stuff first. If that's not the problem, then opti time! :bang:
