I got a message on one of the forums (I've entered 3 or 4 now). The person suspects that the cause is the MLSP switch. It's mounted on the transmission. It is connected by cable to the shift lever on the steering column. It tells the transmission whether you want neutral, 1st, 2nd, 3rd or overdrive by turning on and of the shifting solenoids inside the transmission. I'm going to buy one and give it a try. I already check for the correct cable adjustment and it was right on.

I also lost my Tranny at 51k and now I think the rear end is going. Ther dealer that fixed my transmission said they were having problems with the rear end and in fact that was the first place he check when the transmission went. And no I did not get any help from Ford on the transmission which sucked... Time to go back to chevy!!

Since you've changed out just about everything else...have you looked at the IAC? Idle air control solenoid behind the throttle body plenum. Did your B.I.L have any problems with iding rough before it finally died? Initial symptoms of a bad IAC, you need to step on the gas to keep the engine running or it stalls out.
Test: Try to start the truck with the throttle depressed about 1/4 way. If it starts, or at least tries to start better than before, then it's probably the IAC.
You can also get a feel for your fuel pressure without a fuel pressure gauge - there's a shrader valve on the fuel rail. If crank the engine the fuel pump should come on, and you should get a healthy squirt outta the valve when you press it. (Be careful - wear safety goggles) If not, then check fuel pump relay, or fuel pump.

I have an 87 f250 6 cyl work truck and I think the CC may be bad. The truck has no power what so ever and stalls. How is the best way to check to make sure it is the CC and not something else. I have already changed the O2 sensor. Thanks

thanks for the info. i did buy a gauge and have 40 psi of pressure so i think the fuel pump is fine. i have not looked at the iac yet. i can get it to start for a second and die. then it takes about a day for it to start again. the truck was running normal right up to the point that it died, never rough idling. the whole thing is irritating to me. i have always been able to fix my vehicles until this one. i am probably going to have it towed to a ford dealer and have it diagnosed, then fix it myself. however if the computor is bad i have been told that only the dealer can install it because it has to be programmed. is this true?

I had the samething with my 2004 F 150. My brother-law is a mechanic at big dealership in NY. He told me not to worry about it that it was a common problem with the limited slip rear ends I believe he said some kind of clutch assembly in it and it wouldnt hurt to drive it until I could get it fixed. I had it taken care of about 2months/3000mi ago and everything is great.

Another trial run yesterday revealed that the ghost is still there, so I went to the shop that I trust. The owner drove it and for the first time an expert could feel and hear it. He says since there is no error code that a number of electrical items could be the culprit. He suggests we try replacing the MLSP switch and see what happens and that he can't guarantee it but it's worth a try. He's doing that today and I'll give you the results after I drive it some. You guys probably know this but he says the MLSP gets a signal from the computer as to the gear that the transmission is in or should go to. If the switch is faulty it is searching for the correct gear. HAVEHADIT

#1294 of 2180 F150 very engine runs rough when driving-smooths out at accel or downshift.

Hello, I have a question concerning my 1986, F-150, 8 cylinder, automatic, gas, fuel injected.
On a mild acceleration the engine will start shaking (assuming its missing?) very hard.
If I accelerate hard enough and force it to down-shift, it is like a switch is thrown and it is smooth as silk again. (dry road, cold or hot engine)
Again, I can, for the most part, prevent this by flooring it. But with gas over $2 I would rather do that for fun.
Been reading my Chilton book for help but it does not cover fuel injected engines concerning these types of problems, just carburetor.
Searched the F-150 message board, nothing seemed to match even close.

My 2005 f-150 lariat crew has a moon roof,the headliner rattles every bump is anyone having similar issues.
