need help-s13

[mikulec240]

I just got to drive it today it was running fine. it had old gas in it cause the car was sitting around for awhile. i went to put new gas into the car and after awhile the car would shake when i tried to give it to much gas, or as soon as the rpms got high seeming like it was running out of gas or something doese anybody know what could be wrong? or what should i look for? the car runs fine if u go slow and keep it in low rpms but as soon as u try to go fast it shakes n seems like its dieing,

Does it idles fine and rev's fine when your parked ?
When your driving the car does the car start to jerk and not want to go when you hit 2500 rpms>?

Have you checked your plugs to see if there not arking or fouling the spark plugs.

[ericcastro]

how long was it sitting?

yeah a little more information is going to be needed to help you figure out your problem
is it only under load? as in like what R G was saying is it only when driving? does it rev normally in neutral (assuming its a stick)

check your maf i dont think it could be the problem but if it boggs out over 2500-3k then it migh tbe that.
