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?

ANYTHING helps... thanx

 

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.

Good luck.
