The truck had a check engine code for EVAP leak and I replaced the gas cap and purge valve. When I cleared the code it threw 12 codes would there be a reason for that? Some of the codes I can remember off the top of my head were camshaft, o2 sensors, EVAP purge valve, evap leak, torque converter, solenoid a, and shift solenoid.

Read this guide to get the codes

This video will help you clear the codes

All of the codes that you received have one thing in common, fuse number twenty-three in the engine compartment fuse box. More than likely it will be blown and on more than a handful of occasions I have found the wire harness rubbing against the EGR pipe on the passenger side causing a ground short of this circuit. Another common cause is the cam sensor/synchronizer failure causing a ground short also. The bushings in the synchronizer give out and will give you the tell tale "chirp" which will lead to the sensor being impacted by the synchronizer. Last but not least, general wire rubs through at the oxygen sensor harness against the exhaust, a good visual inspection is usually the quickest way to check this. I've attached some wire diagrams of this circuit and the fuse that powers it, also the fuse location.

Check out the diagrams (Below). Please let us know what happens.

There is a noise that seems to come from my gearbox. It's fine when in 1st or in 5th, but anywhere in between it sounds like something is rattling. Steering and shifting don't seem to be affected. While driving the service engine light has also now come on. The noise has been noticeable for about 2-3 days. Need to have the codes pulled, but the service engine light sporadically comes on, and nothing turns up being a problem.

The only way that I know to determine the problem is to have the computer scanned when the light is on. Have any other lights come on such as ABS?

No the abs hasn't come on. The code that got pulled was a random nonsense one that left us both stumped.

With no code, there must be a probem internal. If I had to guess, I would say a clutch pack may be coming apart. If it was a sensor or trans control module, it would be giving you other problems. Are you certain it is coming from the transmission?

This morning I ran through a flooded street in the dark. Afterwards my engine was running rough like it was missing. After that, everytime I start engine, it runs smooth for about 30 seconds and then starts running really rough. Then, later in the day, my check engine l;ight came on. Engine seems to really be sucking the fuel now.

You probably have an oxygen sensor problem. Before the oxygen sensors begin working, (open loop), the engine does not allow any input from the oxygen sensors. Until the engine is hot enough it stays in a closed loop. Temperature affects emmissions.

Since yours is good in closed loop and the o2 sensors and their wiring were watered down with your adventure, the problem starts perhaps in open loop.

Check the codes and go after the codes it shows.

Hi,

I was having some engine hesitation when accelerating the other day. The service engine soon light came on, and the light panel over the radio began flickering between off, dim, and normal. I got the truck home.

The next morning the truck wouldn't start at all. There is no attempt to start -- no clicking. I've tested the battery and everything is okay.

Any ideas of what could be wrong?--Starter, solenoid, relay switch, alternator?

Check, I mean actually take apart and clean "ALL" mechanical connections from Battery to solinoid and to ground) to include all SOLINOID connections. Insure batt is good or jump from another vehicle.

I have a 200 Ford f150. The check engine light came on and is solid. I have poor acceleration, and a rough idle. I have replaced the fuel filter and it went away for a short time. Unfortanetly it has started again. Do you have any ideas?

If the check engine light comes on get a OBD2 code reader and it will tell you where the problem is located
I had the same thing as you on a 2002 the reader told me what cylinder it even was
These engines have a coyl on each spark plug called a cop (coil over plug)& sometimes they go which usually entails replacing the coil and plug plus resetting the computer, if you use the reader once you have saved enough to pay for it or rent it to your friends

Is the car running ok?. If so have a good autoparts store delete the code from memory. Test drive the vehicle. See if the code returns. If it does repost for more info. Sensors pick up on misfire's for numerous reasons. This could be just a glitch?

Replace coil #1. I generally advise to replace all coils at the same time. As they tend to breakdown in sequence. But for now let's replace #1 to make sure this is the fault?
