Looking for a shop that is willing to help diagnose a check engine light on my 2002 duramax.
I get a p1093 code when towing a decent load 8K+ under load. Like going up a hill. I do not tow a lot with it but when we tow a 36’ travel trailer to and from ocotillo wells from Temecula I get the code usually at the grade on the s2 right after the borrego turn off and then coming home I get it going up the same grade.
This last weekend I got it closer to Temecula going up one of the smaller grades outside Temecula.
I read alot about it and the forums say loss of power / limp mode when it comes in well I’m not a diesel know it all and it really doesn’t seem like I lose power I mean I’m just chuggin along 2200-2500 rpm 45-55 mph and the code comes on I see it flash, I read the code and clear it.
I have been daily driving it for the last 3k miles and the light hasn’t come on. Last time I saw was it a year ago during our annual Super Bowl weekend trip just like this past weekend.
I’ve had a local shop The Truck Shop in Temecula try to figure it out paid them 2 hour of diagnostic fees for them to drive it around and no light. We’ve changed the fuel filter, I just want a reputable mechanic to throw some advise and maybe offer some diagnostics and see if we can figure it out. Anyone in the Temecula area worth trying besides the truck shop?
