#114 of 174 1998 Chevy blazer looses power and stalls
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.

Leaking intake manifold gasket, fairly common on these engines with high mileage.

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
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.

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
Oct 08, 2008 (7:21 pm)
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??
