Since there was some 'washing' going on, pay special attention to ground points. I've had some systems which reacted to weather like an old man's arthritis! The fact that it worked for a while then degraded suggests corroded gound points or bad connectors. -- Will Honea |

2000 Jeep Grand Cherokee 4.7 Engine stalling
I got another auto electrician he said he checked and discoverd that whenever the car stalls current is not been supplied to the coil on the plugs and when he has that kind of issue what he does is that he will change the ECU of the vehicle and reprogram the car to work with the new ECU.
