SOURCE: Blows fuses when parking lights are turned on. Headlights work fine even running lights.

If it only happens when you turn the switchto the parking lights then it is most likely the swich that is the problem. Light swich failure appears to be a common fault with fords

Your alternator should power everything when engine is running. Battery is only for start up. Test voltage with a multimeter when engine is running , should be 14V or more . Any less indicates low alternator output.

SOURCE: Dies when ideling

if u have no check engine light do the following procedure.
Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Engine died while driving, no spark, replaced coil, now starts, idles, runs well at low rpm, but misfires when accelerating. No check engine costs thrown. What should I check next.


Change your ignition module. The distributor is a weak point of the Honda, I will always change out the whole thing than just try the coil.

Motor starts then dies several times when cold


Sounds like the cold start solenoid. It is designed to keep the engine running at a set RPM until it reaches a specific engine temp.

Just turns off on it's own, Wait 60 sec. restart press pedel it dies.


This engine is electronically controlled so the first thing that must be done here is to have the systems control computer tested for fault codes and then do the proper diagnostics based on those codes.

84 crx starts fine and idles fine in park and neutral, but dies immediatly when shifted to drive or reverse. Will run very roughly if pumping accelerator. What's going on?


You might want to check the engine for a vacume leak.Once the rpm's drop it may have a big enough vacume leak to not keep it running under a load.

1995 pontiac bonneville stalls


I just went through lots of troubleshooting and expense on my 1996. Whenever I would lift my foot off the accelerator and was below about 30 mph, the rpm's would starts jumping around and sometimes it would stall. If I gave it a little gas (accelerator), I could sometimes keep it running. It also backfired once in a while. Starts right back up. Also, if I let it idle while in part, it would die after 1-2 minutes.

I ended up finding a hole in the fuel regulator. About a ~$70 part if you get an AC Delco, but very simple to change.
