94 Rodeo Intermitent Engine Light

[Dvfdfireguy]

I have a 94 Rodeo with a 3.2 V6 and 4 wheel drive. I just repalced the Hyd Timing belt Tensioner and the thing runs fine however the check engine light has a habit of coming on at highway speed but goes out when you slow down to an Idle. Anyone have an idea or sugestion? Will having the codes read do any good?

I would check the computer to see if any codes are set.

You need to jump the ALDL connector (behind the left kick panel) pins 1 & 3 then use the check engine light to read the codes.

A good explanation of the flashing light is here:

Its a secondary code.... Good luck with the above mentioned remedy^^^^ You will have better luck useing a snap on vantage that way you can record the problem as it is happening then referance the problem. Checking it while the light isnt on USUALLY wont tell you anything.

yes reading the codes will do some good. it will tell you if any have been set and stored, which can lead you directly to the problem. not all codes are stored, some take a number of hits for that to happen. and the OBDI system is definitely less complete than the OBDII diagnositics on 1996 and on vehicles.

what are you talking about? what are you referring to as a secondary code? the codes stored by the OBD I ?
better luck using a $2500 tool? duh...

and checking if codes are stored isn't dependent on the condition happening at the particular time. the code OBDI diagnostics are not the most complete, but are definitely useful.

What am I talking about........ well I guess you wouldnt know. Yes my friend tool's ARE expensive but f**k up's are even more expensive.
Knowledge is expensive no matter how you gain it.

Good luck guy on your truck. Sometimes As**oles ruin it for everyone.

Sometimes As**oles ruin it for everyone.

I've diagnosed lots of problems with OBD1 systems by just reading what code is stored. OBDII is more comprehensive and easier to get directly to the right part but can be done on OBDI easy enough with some research and testing sensors. You dont need multi thousand dollar tools.
