Q: A grinding noise when applying brakes, growing louder as approaching a full stop. Also, an oscillating sound, as if scratching, then not, then scratching again.
All Part Groups Malfunction Happens always Not applicable
Q: My (service engine soon light) comes on for about two or three days, then goes off for two or three days.
Can this be my 02 sensor being bad causing the erg valve to stick open?
A: I do not think that the o2 sensor malfunction can cause the egr valve to malfunction..... you need to read the codes and determine the cause.... Ed

Q: I am just wanting to swap out my bucket seats for a bench seat and was having a little trouble finding where to buy these seats other than the manufacturer.
A: Look for a place that sells custom pickup parts, they usually have bench seat trade ins, think that the bench seat will fit up to at least 1998, also, you may be able to find a good seat at a salvage yard, assuming that they have a truck cab that has not been exposed to the weather....
These codes would display intermittently and would do it only when the temperatures got cold
outside. Everything always seemed to be ok
when the weather was warm.
So far I've replaced the knock sensor and oxygen sensor.
The symptoms I notice are engine knock and a little chugging. I've also noticed the tachometer pulsing back and forth from a couple
of hundred RPM's
Any ideas? I feel like I should replace one of the three.... ECM, Ignition Module, Crank position sensor.
After replacing the knock sensor the service engine light stays on and will not turn off. Prior to replacing the knock sensor, the light would come on, but after the engine would warm up it would stay off if I shut off the truck and restart it.
A:
Does engine smooth out when warm? Don't guess and replace parts, it'll burn a hole through your wallet.
Are you overdue for a complete tune-up. Scheduled tune-ups is money well spent. You may have a problem with the knock sensor circuit/connector. But I will guess something that is driving the knock sensor crazy. Like a lean condition, weak secondary ignition, and on...
Do you have a DVOM, to check things like the knock sensor/circuit, cts reading, crank sensor, and on..
Do you have a fuel pressure gauge?
Do you have something to measure secondary voltage?
If you have tools you can forge ahead. Without them you are often better off to pay a pro to diagnose the problem, then save money by replacing the defective part yourself. Oh, and you don't want to pay for a pro to look at your truck and say it is overdue for a tune-up.
Q: My knock sensor is only getting 1.5 volts and when accelerating the service engine light comes on and I lose power.
It was diagnosed as a problem with a sensor or part with the distributor. Can you tell me what part it may be and how to fix it?
A: If the knock sensor or the crankshaft position sensor is faulty it can cause your timing to remain in a retarded setting causing a loss in power. Have the trouble codes checked to see what code is setting off the check engine light.
Fuel System Won't Start Not applicable Not applicable
Q: the truck did start this morning, but after a while, the engine begun to slow down, giving signs of shutting down. I turn the engine off and I could'nt start it back on..
A: Check the charging system, battery alternator a faulty alternator will cause a auto to stall, idle rough or not start at all.
Check and replace the sparkplugs if they are older. Worn out spark plug wires can cause horrible drivability and performance.
If you have acess to a fuel pressure test gauge, make sure the fuel pump is delivering the proper amount of fuel to the injectors.
