You may have a Vacuum Leak. May need a smoke test from Garage. They will pump smoke into vacuum lines and find the leak. If your hearing hissing sounds that is a broken vacuum line. Another way to test is run the engine and use a can of starter fluid (Be Careful) but spray along the carb and see where the engine races and you can find the broken line. again be careful I'm not telling you to do that part. Just don't want to get anyone hurt.

I have a 2001 Caravan and it keeps running for over a minuet or two when key is turned off .. Normally it will start & run fine ... But lately it will start and run as if it is runnig barely on 3 cylinders.. I wait about 5 minuets . It starts and runs like a champ again until I have to shut it off and it keeps running . So I tried bumpping the key a few times to on & off and sme times it will help ... Also there is a relay shut down fuse that keeps on ticking & will kill the battery if I dont pull it out . Someties I'd walk away and not hear it and a few hours later it comes on by it's self .. I swear the thing is haunted . I want to sell it because I have 5 other cars and trucks and though it is good riding nice condition I do not want to pass this known problem on to someone else .. Any comments would be helpful ... I am pretty sure it has got to be an eletrictial problem of some sort ... 1 Answer
