Replying to: bones417 (Jan 08, 2009 8:07 am) I thought that most vehicles have that particular wire, and that it/posts can get corroded and cause an unintended voltage drop. Maybe my recollection is way off even for my particular GM V8 which had a problem with that wire: I suppose it could have been the hot wire from battery and not a ground wire. (I do recall being particularly careful when using a jumper cable to parallel that wire, as required sometimes for that car - it looked a bit like I was "hotwiring"/stealing.) |

i have an 04 chevy 2500hd 6.6 that surges at idle. if i let the truck idle it jumps from 1000 to about 1500 every 4 to 5 secs. it only happens sometimes so it's kind of hard for me to pin point the cause of it. plus my engine light likes to come on an won't let me go over 2500 rpms. the code says something like (pressure regulator failure at acceleration). i know someone has to have same problem out there. if anyone can help with this please help.

Just had oil change on 2001 GMC Duramax, and they discovered diesel in oil pan. Took to shop and they stated that all 8 injectors needed to be replaced. This was my fathers truck and do not know if there were any extended warranties on the vehicle at time. The truck only has a little over 130,000 miles. Does anyone know if there are any recalls on the injectors since I have heard so much on these going bad? It is going to cost around $5000.00 to get all replaced with labor and new injectors. Also, would replacing with refurbished injectors be a wise decision due to the cost of new ones.

| I own an 04 LLY Dmax and went to the dealer for servicing and was told that 2 injectors are sent too much fuel. I was told that the work could be as high as $8,000 (C$) which I found outrageous. I researched and found that GM had injector problems with the LB7 engine and problems was suppose to be fixed with the LLY but some had their injectors replaced. GM extended the injector warranty to 200,000 miles on LB7. Does anyone know if this warranty was extended to the LLY? I also read that injector overheat on the LLY? Does anyone know anything about this? | |

i have a 2001 gmc 2500 and it is hard to start when it the outside temp is cold or when the engine is hot. we have given it a snort of ether when cold to get it to start quicker. other wise its just turns till it starts. Also when the engine gets hot after about an hour the power cuts out at 1800rpm's. so far we have changed the primer pump and we have checked all fuel lines and changed one of them. is there anyone out there who may have some ideas for us?.
