    You don't say which eng you got or if only does it when cold. Normal Injected problems with the 1st gen of injection. Throttle body being junked up-remove the air cleaner tube to the throttle body, spray the throtle body inside with carb cleaner spray. Let it soak for a couple of minutes and respray. If it is real black scrub with a tooth brush. Nothing with metal brissels. Also take off the IAC, electric valve on the side of the throttle body and spay the carb cleaner into the 2 holes in it. There are air passages in the throttle body that get plugged making it run too rich and not run right at idle when cold.. The IAC acts like the choke on a carb. If it ain't letting air pass the eng don't want to run right.

1997 Ford Escort stalling when going 35 mph or less.


You may need to be looking at your Torque Converter being in LOCK UP and forcing it to stall because the Transmission is not letting go of the Motor...

You may also have a Plugged CAT CONVERTER

Test the Temp BEFORE and AFTER.. There should be an INCREASE of at least 100 degrees on the BACK from the Front

I have a 2003 CR-V. Tonight I left the lights on and it drained the battery. The battery is only a couple months new, so with a quick jump, it started immediately and ran, seemingly with no problems.......


your battery may not be fully charged yet with the quick jump. let it run for a bit with no lights or accesories, no a\c or heat. everything is run off the computer and it need to be fully charged.

Go out in AM, car is cold, starts and runs fine. Drive short distance, stop and restart, runs fine, idles fine. Drive about 8 miles at 50-55 mph, pull up at a red light, when speed gets down to ~25-30...


The EGR valve is unserviceable which causes a bad or insufficient fuel control for em-missions......Hope this helps you out........EGR valves are not very expensive.

Try disconnecting the battery (both terminals and let set for a few hours) with ALL the accessorries on lights-heater-radio etc. This will draw all power from your system, then recconnect battery, it's worth a try even if it doesn't solve your problem. Bill
