I recently ran into the same codes on my volkswagon, and, through a system of elimination, I was able to find the culprit. Here's my suggestion: Since you've ran a computer diagnostic on it, and the banks are running rich, go through the components and subsystems. 1. When was the last time you had the fuel injection cleaned professionally? A clogged head can cause the fuel injection system to use additional pressure to force fuel past the clog, there by adding too much fuel. A good, professional fuel system cleaning costs about 80 bucks. If you haven't done it in, let's say 60,000 miles, It's worth it to get it done anyway. 2. Is the air filter clean? If it isn't, or if it hasn't been replace in 15,000 miles or so, Go get a new one. They generally run about 10 bucks, but it is vital to the fuel injection system to maintain these minor components. Lack of air, or dirty air often causes the same issue's your seeing. 3. Fuel evaporator valve. Sometimes, they clog, and don't return unused fuel back to the tank. This causes the vehicle to run rich in the air/fuel mixture. They again, are generally cheap, (mine cost 10 bucks) and takes a minute to install. It's a simple plug/ unplug proceedure. 4. Mass Air Meter/ Airflow Meter/ etc... Different vehicles have different names for it. It is the large box that is connected to the intake, it's job is to regulate the amount of air entering the vehicle, and regulate it to make the proper air/fuel mixture. This is mainly a computer issue. Generally speaking, the physical component stays intact, but the sensor/ computer component associated with it goes bad. These items can vary in price tremendously. My first car, a Mazda MX3, had one that went bad, cost 900 bucks. My VW cost on 173 dollars. Do your research on these, try a junk yard, you might be able to get one dirt cheap, and then if that solves the problem, buy a new one down the line. They are generally easy to install, so a home mechanic can replace one in a hour, tops. Hope this helps. My VW was in and out of the shop for two months before we figured it out. I went through all the steps listed about, as well as a few others, and mine turned out to be the meter. IT could be a dirty air filter or a sticking injector.
The engine system urgent service indicator is a warning to turn the engine off immediately. Running the engine will result in severe damage.
i have a 94 cheyenne c 1500 4.3 v6 and it has a vortec
The Service Engine or Check Engine light comes on when the ECU has detected a problem with the emissions system. Do not ignore this light even if the engine seems to be running fine. Failure to repair this can cause damage to the catalytic converter especially if the vehicle is not running good or using excess fuel.
what is the running mate in engine
There is coolant in the engine block when the engine is not running. The engine block, heater, hoses and radiator remain full when engine is not running.
Its a 350 small block
When the service engine soon light is blinking, it means a subsystem of the engine has failed. It could be something as simple as a broken gas cap, or it could be a serious engine problem. If the Explorer is still running fine, it is best to get the codes read at an auto service shop to determine the next course of action.
In the similar situation Mazda dealership thought it's the distributor that needs changing.
The engine sizes for the 1972 Chevy Cheyenne included the 250, the 262, the 292, the 305, the 350, and the 400. The 454 was also offered for the 1973 model year.
There are pages and pages and items that can cause a check engine light. You need to have it checked for codes with a scan tool. After repair light can be shut off with scan tool.
the service engine light is on due to the fact that there is a problem with your truck, this is confirmed by the way your truck is running. you need to get a engine diagnostic check at an auto shop. may just need a tune-up, or the truck has a bad sensor, or engine woes.
The service engine light is the same thing as a check engine light.
The 5.0 is a 305 engine.
Yes with modifications.
My advice would be to set the points at .020" with a feeler gage to get the engine running, and then use a dwell meter to set the dwell after the engine is running.
It is very possible that you have a carbon build up and occasionally a piece lodges in the EGR valve.
Either the bulb is bad or a previous owner disconnected it because it would not go out with the vehicle running. hOW DO YOU GET TO THE BULB??
White smoke is antifreeze, intake or headgasket.
The power of the engine and the maximum speed of the 1972 Pick-up Chevrolet Cheyenne automatic are 300 hp and 60 mph respectively.
FUEL PUMP RELPACE IT ALONG WITH THE FUEL FILTER
if your tailpipe is pouring smoke then you have internal engine problems and need to take it to a mechanic or you need to change your oil
If the engine is running and the alternator is good. If the engine is not running, no.
