1995 RRC. I am following the standard procedure for clearing the check engine light but it is not clearing. Any suggestions? I am assuming that the serial link plug is the one that connects the LED readout? My code is code 48 but everything is running well. 1. Switch ignition on. 2...

Maybe someone can point me in the right direction. 94 NAS 90 has red check engine light, no codes show on the LED readout. I read one post of someone taking the black cover off to see LEDs? How can I tell the code readout is good, or am I doing something wrong? Thanks

I took my truck into a local mechanic that works on all sorts of cars including classic ones as my engine was making a clacking/tapping sound at idle that increased in speed when I stepped on the gas but soon disappeared. I've lived with it for a while but a gas station attendant thought it...

I searched the forum but haven't found anything on this yet. I just started my car after about 2 weeks in the cold here in NH and it just turned 120k. Started right up but check engine light stayed on. Drove it for 20 mins, warmed up nice. Shut it down for a few and started back up and check...

On a 1994 3.9, I get the usual code 45 on my CEL. I've replaced the fuel filter and plugs so far, checked all vacuum lines, and pulled apart the O2 sensor plug and cleaned it. I also ran some fuel injector cleaner in the tank. I can reset the ECU, and drive a good distance and the truck runs...

I was driving my 94 yesterday and after 30 minutes on the road the check engine light came on and about 5 minutes later the truck had no power, I could only go 30 mph. Five minutes later she went back to normal but my check engine light is still on, what should I do?

Hi, My check engine light came on today. I searched this site and found many answers from "if the truck is running don't worry about it, to disconnect the battery, to study the fault codes, etc." My truck is running great. It came on today for no reason when I was idling in light rain...

O.k. I keep throwing a p1317 code, which says rough road fault. I have took the sensors out cleaned them. But I clear the code and within hours there is another fault. The real Question here is if it throws a rough road fault does it go into default mode? or is that just for engine codes? I...

I decided to replace the rattling cat on the 97 ST. Instead of buying the whole new Y-pipe, I went to the muffler shop and had them weld in a high flow magnaflow. I thought this would do the trick. Well, the rattling is gone, but I now have a reoccurring check engine light. I don't know the code...

I have a 97 SW that is getting a P1176 error code fairly frequently. The check engine light comes on and then will go out after a few days. In another day or two the check engine light comes back on with P1176. Every now and then it idles a bit rough. Other times it hesitates a bit at 2500-3000...
