New Here please help

Hello all I am new to this Board some of you might know me as Icudie on G20.net but since no-one has answered my thread I thought I would try here so here it is........

Hey guys as of yesterday my car started bogging whenever I accelarate from a stop also while in Drive but Idle the Idle jumps up and down between 600 and 1100 or so, after I get over maybe 30 everything seems fine its under 30 that is really bad, alomost got hit cause I couldnt clear an Intersection in time...

My Ideas are

Bad Fuel Pump
Bad Fuel Filter
Bad Gas (went from 89 to 91 with about 1/4 tank left of the 89 and it only started to do this when I got to about 1/4 of a tank) I heard mixing diffrent octanes can be BAD...

Please Help I need to go see Spider Man!!!!!

mixing octanes doesn't hurt a thing, have you checked your air filter recently?

Moved thread to maintenance..good luck!

you may have a bad oxygen sensor, check that out first.

Possible throttle position sensor. They are known to cause a jumping idle. Does your car also have a high idle (1500 to 2000)?

checked/changed your oil recently?

whenever mine gets low it does this.
