Recommendation: altho mine is not much of a nuisance at this time, it would probably be best to just replace the blower fan control switch and that will take care of it. I am going to drive it about 60 miles today so I will give an update. The engine had a bore and stroke of 4. This is where the pressures change as well as the temperature. If so, where is that located on my engine. This engine was replaced in 2002 by the 5. I replaced all plugs, plug wires, rotor and cap.
Cleaned it with a wire brush, reset light by disconnecting the battery and that seemed to fix it. The older models put it right at the entry of the evaporator cold… The 1986 Chevrolet Suburan came with two engines. A few weeks later I changed the Wires. Pulled the plug, and it was all dirty and corroded. Then it developed a rough idle and low power output and the Check Engine Light came on. If you will look under the hood you will see a placard somewhere on the radiator mounting bracket or under the hood itself, with the engine size listed. But if you follow the line that comes out of your condensing coil radiator thing in the front toward the firewall you should be able to see the connection where it goes.
The 4300 engine was retired in 1998 by a newer 4300. The 7400 engine was featured in the Chevy line of trucks, such as the 2500. The 7400 has an overhead valve configuration with two valves per cylinder. Seemed to fix the issue. The door lock will activate to confirm the programming mode. It was basically multiple misfires.
I have a 1997 Chevy Suburban that I have been having some issues with. Very hard to tell these engines apart. After changing the wires, I started it up. Looks easily accessible… You can disconnect the battery for about 5 minutes and this will clear the check engine codes stored in the computer. Please the check engine light is still on and occasionally blinks.
Release the door unlock switch. No oil leaks from what I can tell. I truly appreciate your help so far! One day it just started, and my step father checked the codes. The truck engine was rated at 255 horsepower and 330 foot-pounds of torque. If the problem that caused the code has not been repaired the check engine code will just happen again.
The V-8 engine had an overhead valve configuration, with two valves per cylinder. Ok so I pull 7 wire off both ends and reattached. During 1997 Chevy still had a big block engine, the 454 cubic inch. The premier Vortex engine during 1997 was the 4300 or 4. Your local auto parts store will have them. It was still having a hard time starting. The engine was designed for power and was a monster gas eater that got 15 mpg at best.
Vortec engines are the base engine used in all Chevy cars and trucks and come in a variety of horsepower and torque ratings. From what you describe it sounds as though it has a bad injector bleeding down or the fuel pressure regulator is blown causing it to drain the fuel system into the intake. The location of this is not too familiar to me though. Close all the vehicle doors, insert the ignition key in the vehicle's ignition. I changed the Distributor and Rotor.
Also listed there will be some other inforamtion like Spark Plug gap. The anti-fouler shields the spark plug's electrode and keeps it from fouling out. The only way to get the check engine light to not be on is to repair the problem then clear the codes. The guy said it was a 7 Cylinder misfires. The engine had a bore and stroke of 4. Basically the anti-fouler screws into the head then the spark plug screws into the anti- fouler. It was rated at 290 horsepower at 4,000 rpm, with 410 foot-pounds of torque at 3,200 rpm.
Need to fix so I can smog it!! Is it possible it is still the pressure regulator? I am getting service engine soon light again, checked codes and it is only one now saying cylinder 4 is misfiring. The 454 cubic inch engine was derived from the Chevy big block 454 cubic engine of 1974. The king of the Vortec small block engines during 1997 was the 5. Press and hold the door unlock switch. . Try using a spark plug anti-fouler on cylinder 4. Js08016 answered 3 years ago Worn engine components, as mentioned above, can repeatedly foul out a spark plug on a single cylinder.
