But if you have a broken vacuum line, faulty map sensor or a problem with the engine where its not pulling good vacuum and not from air rushing in the motor will be too rich. It has the original Tuned Port 5. I have been over and over my engine, so may times, I think I could disassemble the top half in my sleep. The coloring should match on these plugs. When you remove the light socket to gain access to the daytime running light you often see the problem right away. I examined the injectors again with just a flash light. Not the most accurate method of metering fuel into a motor but it works.
He also checked the timing only to find that it was ok. Opti-Spark is now the standard ignition system on 5. The Mass Air flow sensor is back in 94 andi s one of the primary sensors for fuel control. Recommended location for the fuel pump is close to the fuel tank. I am not yet totally convinced it is the injectors, but at this point any direction is better then none. Above that very likely to have a problem.
But the Code 42 persisted. It is all stock with the exception of the intake manifold. That changed as soon as I mashed the gas. The filter was shot too. Either will certainly give you problems. Half of them are carboned very badly some of them have deposits on only one side. The link is: After resetting the base idle, the truck doesn't surge.
I have used propane, carb cleaner, and wd40 to try to locate leaks. You may have a vacuum leak or other problem with the setup. It is really strange that the miss disappears under load. On these units the replacement lamp has a clear shell. The intake is now clean, if you continue to have the idle speed control problems you may need to seek the help of a professional. Poor grounds gives me more weird issues than anything else in the wiring.
Using high volume oil pumps are really bad to cause this problem. You need to get back to basics with this one -- perhaps fuel pressure is a problem, or distributor -- losing spark under load. On almost all the plugs the deposits were only on one side. So when diagnosing fuel issues. I didn't think the O2 could be bad, but pulled it anyway and tested it. There's a few interesting things about this automatic set up.
If you turned the motor off and restart it, the idel was fine until you gave it some gas and then the idle would go up and down or stay high. If both plugs are nasty black then we do have too much fuel. Lets start with the high idle. The B2L indicates this car has the 5. Not only does it look unattractive, but these vehicles often fail a state safety inspection. I have had plenty of the things dead right out of the box. Do you know anyone with a scanner who could look at the datastream for anything out of the ordinary? The thing was waaay retarded.
Wow, how easy is this? The wiring for these systems are not interchangeable, without modifyingthe wiring harness. If it runs good cold and poorly when warm that can possibly be an o2 sensor. The calibrator provides a wider pulse width on startup to provide a richer mixture for a cold engine. We made it about 15 miles before the car began to lose power. The two and three wire light sockets cut and splice into the factory harness. Put 12 v to tank fuel pump, it pumps fuel and starts. Relying on his instinct to take customer claims like mine with a grain of salt, Sjoberg went back to basics.
I found one on the pb port and repaired it. Then check the pressure in the fuel rails. Finally I decided to get it fixed and bring it to my friend's garage. For 96 a combination crankshaft position sensor and cam shaft position sensor perform the timing functions on all the 4. Its also been running a little hot, and i think im loosing a little coolant internally. A 30 % increase in horsepower, torque and fuel economy is seen over carburetion.
