Engine Performance problem
1992 Chevy Blazer 6 cyl Two Wheel Drive Automatic 218000 miles
Hello, I have a 92 Chevy s10 Blazer w/ vortec engine and auto trans (2Wheel Drive). Yesterday when my wife was driving it, it started stumbling and bogging down on her. She pulled off of the interstate into the E-lane and started it back up. It would immediately start as normal but as soon as she would hit the gas it would bog down, and either lope or cut off.I had it towed to our house, and once I got it home, I tried to start it, it started right up, but as soon as you hit the throttle it would bog down and die. This morning I went out to start it and now it wont start.I have checked the exhaust to make sure there is pressure coming out, and from what I can tell the cat is not stopped up.I have also checked for spark and it has tested good also. As far as the fuel, I took the line loose at the filter and turned the key to on and it sprayed fuel everywhere, I did not check the pressure for I dont have a pressure gauge, but I also checked it at the fuel rail and it seemed to have quite a bit off pressure there also. Could the timing have jumped or is there something I am missing?Any help would be greatly appreciated. Thanks in advance. Hope you can help me.
And I forgot to menton, when did start it yesterday, it would sometimes back fire through the intake, I am thinking it is the timing but just wanna get a second opinion.
have the same problem?
