The van ('95) just started to do this 10 days ago. I start it, it runs fine for about 5-15 seconds, then if I give it gas it doesn't rev (no power/doesn't move if in drive or reverse) seems to want to die, too much gas and it almost backfires, but rpm's don't go up and it struggles. I baby it of 15-20 seconds and once I get it to rev a few times it's fine. Drives fine until I turn it off and start it again. Seems to be getting a little worse...it's died a couple of times lately, and not getting fine as fast after a few revs.
Seems like some computer version of a choke not working right, but my experience is with mechanical cars (like from the 60's). My daily driver got totaled (I'm fine), so the EVC is now my daily driver.
Help…Any thoughts?
