Probable electrical / computer issue with 4cyl 98 Stratus. Help??	Sign In

Hi,

Recently I've been having a problem with my 4-cylinder 98 Stratus and I can't figure it out. I'll be driving down the road, and the car will shut off. The instrument panel goes dead (speedometer to zero, turns off cruise control, etc) and the Check Engine light comes on. The rest of the electrical seems fine - the headlights and stereo don't cut off. If I'm going at a decent speed (or if I hit the gas in time when I'm going slow) the car will kickstart back up and run fine. If not, it just stays dead and I have to rip it into park and start it back up - it almost always starts up just fine.

It happens when it's hot or cold, at idle or at 70mph, any time of day. We drove it hooked to a scanner for about 50 miles while the problem happened and it doesn't trip anything. The throttle body was dirty so we cleaned that out and that improved performance for a short time, but the problem came back within 100 miles.

Has anyone seen or heard about this before? Short of putting a new computer in, I'm not sure what to try. Thanks!

Marcus

No, it doesn't. It only indicates that the engine shut off unexpectedly

Hook up fuel pressure gauge and see if fuel pressure drops at same time. If it does, fuel pump is on its way out, or possibly the fuel pump relay is shorting out.

Being way2old is why I need help from younger minds
