Here's a code reader for my 1994 Ford Van, I hope I can find out what's causing it's poor performance now. The new plugs, wires, distributor cap and rotor took away 95% of the jerk but its still runs sluggish. I'm thinking the oxygen sensor and IAC sensor needs to replaced and if it has a MAF sensor the delicate wires in it need to be cleaned with CRC electric contact cleaner..

The scanner cost $25, with the optional 6' wiring harness $50, that's not so much, It will save me time and money from driving back and forth to Autozone.

This one actually shows the number of a code not blinking lights that have to be counted.

I have one of those for my '92 F250, but there is so little data available in the pre-'96 OBD2 cars that is was never very useful. I hope it works better for you than it does for me.

I don't think any code reader(even the newer OBD11 system) is always 100% accurate and reliable in detecting whats actually causing a problem. I'm hoping by studying the book I'll find important in between the lines information that's often needed to isolate and fix the problem.


Taking it to a dealer to get fixed amounts to an expensive parts changing party.. I read a thread on a truck fix-it website which dealt with the same symtoms I'm having and the poster's dealer was up to $1300 and still hasn't fixed the problem, and the dealer is supposed to be one of the best truck dealers in the posters area.


I doubt my 1994 Van is worth $1300 running properly. :laugh:
