Two problems fixed thanks to this forum!

[Richw001]

Well, all I can say is this forum is the better than any tool in my tool box.

About a year ago I had the message center come on with service 4x4 I didn't have any idea so my nephew found this forum for me and after a little searching and reading I found that it is a common problem with the switch on dash just needed to add more sodder to all the points, I did this and the light was gone.

 

My next issue has been bugging me for the last 4 months or so, the truck would start fine when not warmed up and very tough to start once warm, and would idle very poorly to the point of almost stalling out and seemed to be getting worse.

The service egine soon light had been on for a while but all it said was emmision control malfunction and o2 sensor, changed the sensor and did nothing, came here posted a question got pointed in the right direction and did more searching and reading and found that it could be a number of things but the more common items were EGR valve and Fuel Pressure Regulator. Started with the easy one first pulled the vacuum line off the FPR and gas dribbled out of FPR (it's not supposed to) and truck immediately idled better, so went and bought a new FPR $49.00 installed it, and now the truck runs great warm or cold.

 

Now my next issue i'll be searching for is how to get the emmision control malfunction code to go away.

 

Anyhow, thanks for this forum and all the great advice.

take it someplace that reads codes for free they should be able to clear them. unless they have something against clearing emmisions codes in your area. in witch case you'l have to take it to a emmisions place and they will have to check it out.

Yup, AutoZone or O'Reilly's will scan and clear them for you. At least around here they will (if they aren't real busy).

 

And this is why these forums are so great...And why some of us stick around and annoy the world.
