'94 Chugs going uphill

My '94 has started to chugga chugga when I am driving up a winding hill and need to let off the excelerator and then accelerate again. When I do, it chugga chuggas until I come to some kind of steady speed again. It has also started to have little backfires sometimes as well. It runs fine on flat grades. THis has 100,000+ miles on it. Any ideas?

Thanks!

When was the last time you tuned it up? Is this Carvan a 4 cylinder? This sounds like it may have something to do with the spark, like one of the following; bad plug wires or fouled spark plug. Sometime bad gas will do this. If you only run 87 octane in your van, run a tank 93 every so often just to clean it out. A good turn up would probably cure this with some new plug wires they don't last for ever. Good luck. RIde On, digimon

This sounds exactly like what mine is doing now right now. I took it into the dealer yesterday and they ran their computers on it and said it is bad Sparkplugs and one bad Sparkplug wire. I didn't want to pay $220 for them to replace them so I went out and bought Bosch Wires and Champion Plugs for a total of $40 bucks. Will be putting them in this weekend.

Just wondering, is your "Backfire" sound right in front of the driver and do you feel it in the accelerater pedal?

Put them on yourself is a money saving thing to do. It's really very easy. Just one note, take off and replace one at a time so as not to confuse the order. May not be a bad idea to replace the distributor cap and rotor as long as your doing it sometimes the cap gets cracked. A cracked cap may also cause your car to run ruff. Just do it the same way move one wire at a time. And since you will have to take off the air cleaner to do the back plugs why not replace it too, if it needs it. A good clean air cleaner will better for your gas milage. Cheak all your fluids and battery. Now you've just done a $350.00 tune up for about $45.00. It only took you about an hour. Good Luck!

I'm betting fuel pump... #1 symptom

I'm glad to say the dealer mechanic was right. New wires and plugs and my 92 Caravan is back on it's feet. No more power problems, and no more popping. I hope yours turns out well CeeCee.
