#111 of 142 high idle on 97 blazer by horsey Mar 09, 2008 (6:19 pm)
I have a 97 Chevy blazer w/ V-6 Vortex engine. About a month ago it starting idling higher than normal until it warms up. When you are on icy roads and come to a stop sign, if the idle hasn't come down yet, it's like trying to stop with one foot on the brake and one on the gas, which isn't good!! The high idle eventually comes back down after awhile. One buddy though it might be the throttle positioning sensor and another buddy thought it might be the idle air control sensor. The check engine light doesn't come on though, so I was told I probably can't get a code. Anybody thoughts would be greatly appreciated.
#112 of 142 Re: Chirping Gates serpentine belt fix [tommygemini] by jlflemmons Mar 10, 2008 (8:02 pm)
Replying to: tommygemini (Mar 09, 2008 2:43 pm) I finally had to give up on the Gates belt and go with Goodyear. A trusted mechanic told me they have had problems with Gates serpentine belts chirping and squeaking. He said it is because the Gates has continuous grooves with no breaks and can trap oil and dirt.   Since I changed to the Goodyear belt I have had no noises in over 3 months. Seems to be fixed.
#114 of 142 1998 Chevy blazer looses power and stalls by bigt442 May 22, 2008 (11:26 am)
I have a 1998 blazer that has had the fuel pump and filter replaced. It still seems to lack power and sometimes backfire or burp back thru the throttle body. fuel pressure seems to be with in tollerance, but have noticed a water leak at the back of the intake. So with that leak could a vacume leak cause it to run like this also. I have had a code that tells me that it is lean on bank 1 also. any help please.

Replying to: bigt442 (May 22, 2008 11:26 am) Leaking intake manifold gasket, fairly common on these engines with high mileage.

#117 of 142 1998 Chevy blazer stalls. by bigt442 Jun 01, 2008 (9:58 am)
I have a 1998 chevy blazer that I have now replaced the fuel pump and filter. I have also replaced the intake gaskets, mas air flow sensor and have tested all other sensors. All of them have check fine.The only other sensors to be check are the cam and crank. So now here is the problem, It will start but when you go to give it the gas it will stall out and then it may set a few moments before it restart. I am lost at what to do.
#119 of 142 2001 Blazer cyclinder 5 misfire by lincservices Sep 16, 2008 (2:31 pm)
2001 blazer 4.3 4wd - Repolaced fuel filter, air filter, plugs, cap, rotor, wires and oil change. No code until 15 minutes after getting to temp and then OBD gets a code for cyclinder 5 misfire. Would the coil cause this? Or do I need an injector. My mechanic stated that if I replace the injectors, I have to have a "spider" setup, but during research, there is no "spider" for that year, just the injectors and fuel pressure regulator.
