Diagnosing a problem

mnewxv · 08-27-2008, 04:54 PM

check the plugs since it sounds sorta like misfiring. If plugs check out, check the injectors. also try and get a code on the engine light, that could help a lot.

Is there a trick to getting the code on the engine light ?

I assume it has an OBD 1 system. I'd take it down to autozone and see if they have a scanner. I have gone there before with OBDII vehicles and they had a scanner and scanned the check engine light for me free of charge. If they dont have a scanner that will work with OBD-1, then take it to a honest mechanic shop, I say honest because some might want to charge you for checking the codes.

They all charge 150.00 to read codes where I live.. so I bought the OBII scanner for myself. Havent found an OBI scanner yet. I like owning them as I have 6 vehicles. Saves $$$

Check the Sticky'd threads in this section on how to check for the CEL codes. You don't need a scanner, just a little piece of metal wire...

i believe you can just take a little paper clip and stick the ends in T and E1. then turn the key to on and watch the engine light blink.

ooooo...oo... is code 52. knock sensor.
you get the idea?
just count the number of flashes.
