I have a 1998 Dodge Grand Caravan with 215,000 miles. The inside is immaculate. It's never leaked a bit of oil (or other fluid for that matter). The oil has been changed every 3,000 miles and all other required maintenance has been followed. It runs perfectly. In the summer. (Hence the nickname - "Snowbird") On VERY cold days, it doesn't idle properly. It will start right up without any problems, but the low idle struggles to hold consistently. When I start to drive, and increase the idle with gas, it runs fine. But as soon as I slow to stop or turn, I lose power and the engine shuts off. I can immediately start it back up, give it a little gas and go again. It starts back up every time. I can usually tell just before it is about to die as the lights dim as the van struggles for power. (It died about 7 times on the way home from work today) I've taken it to two different mechanics with no luck. (Of course, it usually isn't cold enough for the van to act up). My father-in-law said he thinks it is just the internal computer needs to be replace. (Which is pretty expensive - and just his "guess") Plus, how can that be tested without just buying a new computer? I'm willing to put some money into the Snowbird, but I am sick of paying mechanics to NOT fix the problem. Ideas?
