Question about 1994 Ford Crown Victoria

Check engine light

1994 Crown Victoria LX started stuttering when accelerating,now the check engine light is on and it'll barely run.Any ideas where to start? When the problem started it seemed to run better when cold then when it warmed up it would hesitate when accelerating. The problem started about 6 months ago and got progressively worse until the check engine light came on. I don't have a code reader just basic tools and a very tight budget. Any help would be greatly appreciated. Thanks.

It probably stutters more when going up steeper inclines also, if I'm correct. There are a couple of solutions that worked for me. The most simple one was replacing the serpentine belt, after realizing that it was 160K overdue to be replaced. That made a huge difference on that milage, and the acceleration in addition to mostly cutting out the engine stutter. The second thing was a vacuum leak. You can find diagrams of the vacuum hose layout online, then follow the lines with windex while the car is running, and look for bubbles, just as you would for a leak in a to the light, i agree with him^ Hope this helps some.

Hello? Emission problem 1994 crown vic here...

I owned one of these. There is a groove under the butterfly horn of the throttle. There are 8 bolts and a $10 gasket. Often the EGR passage is clogged and it throws off the calibrations and when you clean this groove the engine will run much better.

2005 crown victoria sport lx 4.6. Was idling along in traffic and car just died. No stutter or anything just died. Pulled over to the side, turned off the ignition let it sit a minute, started right back...

Electronic's ,go figure .. Not all gliches set code's . Could be any number of thing's - sensor's , modules etc..... A professional Tech would have trouble finding what was wrong , even with profession diagnostic test equipment , scanners etc..... It would be better if it died an wouldn't start back up . Check for TSB'S -
technical service bulletins. Check battery an connection's , loose wire's for sensor's etc... engine . That's about all you could do. Hooking up a professional scan tool an checking engine sensor data inputs to the PCM - engine computer . There maybe a bulletin for a reflash of the PCM .

Check Engine Light Crown Vic 1994 - runs great

When the service engine soon light (Also called the check engine light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

'94 Ford Crown Vic Headlights

They are changed from within the engine compartment... at the rear of the headlight bazels... if it's the side on the battery you may have to remove it.... also don't touch the bulbs with your fingers as that shortens the life of them.
