#117 of 174 1998 Chevy blazer stalls.
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 174 2001 Blazer cyclinder 5 misfire

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.

hi,i have a 1999 blazer with 4.3L engine.the fuel pump went bad so i waited about 2 weeks then replaced it when i had the time.now the engine runs very rough and the exhaust is black and smells very sulfery.after driving it awhile i got the service engine light, the code reader shows p1133 and p1153.when i put a pressure gauge on the fuel rail test port it's reading 80-90 psi well above the 60-66 psi it should read. before the fuel pump went bad and i replaced it the car ran perfect.the manual i have for the car does not tell me what these odb codes mean. any help or ideas would be greatly appreciated

The water leak shouldnt cause a vacum leak although it may! But the code lean on bank one tells me that the o2 sensor is bad, also check to make sure the firing order is right as well! The code says the o2 sensor in bank one is bad which means the sensor befor the cat. try replacing that one. there should only be 2 of them on that model
#123 of 174 97 Jimmy with a miss

97 GMC Jimmy with a V6 Vortec, motor was bought from Advance and has around 40000 miles. I didn't put the motor in, it was already installed when I bought it. Hope someone can help me with this miss problem, I will try to explain it the best that I can. First off, new plugs, new plug wires, new coil pack, fuel filter and air filter. Catalytic converter has been removed. No Check engine light is on. The vehicle starts perfect and idles perfect, but when you go up a hill it sometimes has a bad hesitation like you are letting off the fuel back and forth, give it more gas and it quits. Then sometimes on flat ground at 55 mph it does the same thing. Sometimes I can pull into a parking lot at 3 mph or at an idle and the motor has a violent stutter to it. That has only happened twice. So can anyone enlighten me on this subject??

Actuall it is not the motor. my moms blazer is doing the same thing and it is a factory gm motor. I am trying to track down that problem this week if i figure it out i will post another message to this problem.

In some older GM transmissions there was a problem with electronic solenoids sticking and not allowing the trans. to downshift out of lockup. This may be part of your problem
