Default My service engine soon light is blinking/car is sluggish etc... ??

Well I got some gas and when I started driving I noticed some light ticking. The service engine soon light is blinking and then stays off and then starts blinking again. Also the car feels extremely sluggish, and the exhuast backfired a couple times. any ideas?

this sucks

blinking is a misfire... check your plugs wires. Is it at idle or driving

its doing everything while driving. and I did have to take off one of the plug wires last week when I was changing my AC lines, I went to check it out. its on, but is a little slanted, Once the car cools down im going to reach down there and hope that thats the problem.

I think it might be the opti. I went out there and made sure that plug ws on there good. I took it for a drive. it seemed sluggish. and I didnt notice the check engine light this time. The engine seems to pretty rough and I think its shaking my exhaust and thats what is making the ticking noise. Is there anyway to confirm that it is the opti?

At this point, I am going to claim this as an opti failure. Your misfire code is going to be random cylinder. Betta get ready to pull that ****!!!!!

And whats with the no-opti love????? Its not that difficult to change (at least not when you have done it 10 times).

This would be a GREAT time to remove all of the bad stuff on the car and get it deleted from your computer.......

well I took it to autozone it came up as a bad 02 sensor. Bank 2 sensor 1. I dont know a whole lot about exhausts. But I have LT headers/True duals. So im not sure where to look?

Replace your passanger side front 02 sensor. It should be very easy.
