I've got a problem with my Astro Van that I could use some help with. This van idles fine, but from a stop to around 30mph, I get some noticeable acceleration problems. It feels like a miss or sputtering and seemed to be just before hitting 2nd and 3rd. It doesn't do it every time, but it's most of the time. It may do it a little when cruising ( could be my imagination), but is more common when accelerating from a stop.

I'd appreciate any help. This is my work van and I need to keep her on the road.

 

Might want to check the transmission. mine did the same thing before i had to replace it. go ahead and get it serviced.

 

Thought it was the transmission, so I replaced it. Same problem.

 

ah sorry i didnt see that.its probably something with your fuel intake.

 

Finally saw a code today. P0300 : Multiple/Random Cylinder Misfire
Think I'll replace Dist. Cap Monday.

 

Replaced Distrib. cap Monday and the Astro is running great. Took it out first thing this morning and no problems! May have solved this one (knock on wood).

**update: 7 days and no problems...

 

I am having the same issues with my 1999 Chevy Silverado 1500 4.3L. Runs smooth at idle, but when go to accelerate while in park It feels like a miss or sputtering. The truck has new fuel filter, dist. cap, wires, plugs, and air filter. I am at a loss.

 

I want to make a note....no check engine light on and no codes.
