Hey, so one day I decide to put in the cheap gas and little did i know it was going to affect my car this way. MCS all stock and now it feels like it misses when accelerating between 2-3k rpms. Its pretty bad too kinda pisses me off actually. I changed the plugs and wires because I thought this would fix it... but NOOOoooo. So now every time I shift, the car jerks all around. Do you think it's probably dirty injectors, or maybe just the bosch platinum 4 pulgs?
Have you run through the tankful of cheap gas? If you haven't gotten rid of the cheap gas, you are still experiencing it. Until you can get back to a minimum of 91 octane high quality (something like Chevron Supreme) gas, there is no way to even begin a troubleshooting effort.
oh... ya, definately. this was about 5 tanks ago. It's just bothering me enough to post about it now. I'll take a look at the electrodes on the plugs today.
Similar thing happened to me and I added a bottel of the Octane boster to the tank with another fuel injector cleaner. But I would start with the Gas filter first.
