Contour Enthusiasts Group Archives Forums General Troubleshooting 96 2.5 starts, then stalls.

Yes I searched. 96 2.5 turns over, idles fine, but randomly stalls out. If it is put in gear, idles really rough, wont rev over 1100 RPM, even at full throttle. Check engine light is on, but my car is stuck at work. Also the OD light is flashing. I took the battery out, and put it on the charger. The voltage started jumping around, and it steadied out. I am prone to believe it is a shorted battery, but it is only 8 months old. I have replaced the alt, the fuel pump, the coil pack, and the MAF in the last 3 months. Any help?

edit: also, the speedo will go from 0 to 130 while in park, and all the lights dim unless I floor it while in idle

Replace the intake gaskets and have the battery tested. If the battery is good check for voltage drops on the battery cables, ground connections, and power distribution box.

The gage problems are just due to low voltage.

Battery check is good. Would a low voltage also give me the tranny light? Now the car starts good the first time, stalls out after a minute, and starts again, but only for a second. When it started good the first time, it ran until I put it in drive. I am worried this might be a tranny issue. Any one in NE OH free tomorrow...haha..

"Would a low voltage also give me the tranny light?"
Yes.

"When it started good the first time, it ran until I put it in drive."
Is it a ATX? If it is then, it could be a bad VSS.

Scan for CEL codes and post.

Yeah, its the ATX. I have to get the car moving before I can get some codes read...haha. Going to replace the ground cable tonight.

If you haven't changed the ATF in 30K miles, now is a good time to do it.

If you have problems with the car while it is in Park with the engine idling, etc. I'd address that first. With engine running in park, spray some wd 40 aroudn intake ports. Does the engine speed change? If so, I would then do a upper/lower inktake manifold cleaning with gasket replacement as listed in howto's.

If engine still won't run properly in park, I'd chek your plug wires. When did you last change the plugs? Also, check cam and crank sensor. Check throttle speed sensor. Check the ECT sensor - not the one for the temp gauge. The ECT temp is used by atx, computer, etc. Also check TSS.

Lots of sensors to check for sure......
