#583 of 2018 Sonoma heater core replacement question. by pbernard Mar 28, 2005 (3:14 pm)
Hi, I have a 1991 GMC Sonoma, 4x4 with the 4.3L engine. When I bought the truck new, it did not have air-conditioning. The dealer had a after-market air-conditioner installed. I now need to replace the heater core, and do not know if I need the one that is for air-conditioned models or non air, as it was when I bought it. My question is: If a after-market air-conditioner was installed, was the original heater core replaced with one for air-conditioning? Thankyou in advance.
#584 of 2018 Re: If your carpet is wet..... [gmjon] by bbarlow Mar 28, 2005 (8:54 pm)
Replying to: gmjon (Feb 21, 2005 11:52 am) I am having the same problem w/95 s10.No water thru windshield,but lots of water thru doors when it rains or even when I run the wipers. Air bag light just started coming on intermittently. I am afraid the airbag may deploy just for the heck of it, or NOT deploy if I'm in a wreck. My mechanic said that the little seal that runs around the door had a hole in it,and to fill the hole in w/ silicone, and that should stop the leak. I'm pretty sure the sensor fix is expensive.

Replying to: dgh50 (Mar 28, 2005 7:19 am) Thanks for the additional info on the drain. I knew there was a recess in there but wasn't for sure if it was hex or square. And the service manual wasn't helpful at all, just the standard "remove the petcock" statement. Will be picking up new hoses as well. Is there a gasket that goes between the housing and the intake or does the gasket around the thermostat do the sealing?   Will have to check to see if I have a 3/8" allen, if not, a good excuse to get some more tools.

Replying to: jae5 (Mar 29, 2005 11:34 am) Glad to help. There is not a gasket between the housing and the intake. The gasket or "seal" that goes around the thermostat is all there is. Just take note of the position of the old seal before you remove it, because one side is slightly different than the other.

Replying to: londog77 (Mar 20, 2005 11:31 pm) Have you checked to see that your fuel to air mix is right? You may be running lean, or it may not hurt to check your ignition system. Good luck!! Replies to this message: 97s10ss (Apr 01, 2005 8:07 am)
#588 of 2018 97 sonoma 4.3 engine misfire-help by dtl379 Mar 30, 2005 (1:24 pm)
I have a 97 GMC Sonoma with the 4.3 X throttle body injection. About 1 - 1.5 years ago it started misfiring.Ihave replaced the plugs wires, cap and rotor about 5 times. We also replaced the ignition ciol, fuel filter, air filter, PCV valve, and cam position sensor. On top of that, we have run injector cleaner, repositioned the distributer, timed the motor, and have run throttle body cleaner. You can smell carbon sometimes, but I've been told it most likely not the injectors. we are still recieving random misfire codes on all cilinders. In October of last year, the service engine code came on for "hard misfire" and "cam position sensor circut malfunction". But here is where it gets fun. Before we fixed the engine, it stopped missing. It ran rich, but never missed a beat. Anyone have any idea at all? My mechanic is stumped, and the truck has been the talk of the shop. Please help!! It only misses at steady driving speeds above 35 MPH. Replies to this message: mlaplante (Jun 07, 2006 2:12 pm)

I'm getting spark and fuel, but the truck isn't even trying to fire up. Please Help.

#590 of 2018 '94 s10 problem by choppercustoms Mar 30, 2005 (7:32 pm)
I have a '94 S10. Whenever I start my truck it starts okay. Once i rev the engine it begins to sputter and backfires some and then finally dies. It also has a smell of gas after reving. Im not sure what the problem is. I've already changed the fuel filter but that didn't help. Please help.                                     Thank you Replies to this message: stenzyman (Mar 31, 2005 8:06 pm)
