1999 olds 3.4 Van

Ok,

Here is the deal..

When it's cold if i take off it sputters back fires and dies.. or runs like it is a 2Cyl go cart.. After it warms up it is ok but during crusing it. has a miss from time to time.. Check Engine light comes on if you make it suptter when cold.. it says {miss fire all cylenders) or somthing like that...

Any ideas? I replaced the fromt 3 spark plugs because i was short for time but that did nothing


thanks,

Jason

If the check engine light comes on, take it to Autozone if there are any in your area, or some other auto parts store that offers free checks of your diagnostic system. From there you can get info on trouble codes that are stored in your vehicle and you can come back here and post the results to get some help.
