Drive Train / Driveline Malfunction When accelerating Always
Q: The transmission shifts hard. Or stay in 1st too long before shifting to 2nd.
I changed fluids, and it was better... but now it's back to hard shifting again. Sometimes, it will shift alright.
A: A lot of the Ford produsts are sensitive to changes....
For example, if you change the throttle position switch, the transmission shift points have to be recalibrated, I recall that only Ford can do it....
Try unhooking the negative post on the battery for 1 minute and see if the computer resets for you.....
Or next is have the dealer check and diagnose for you...... good luck... Ed
Q: After stopping, i notice smell of gas. Just under the driver's door i notice a few drops of fluid, i check and it's defintely gas.
I take it to a dealer (Toronto, Canada ..Rowlands Lincoln) they say they can't detect where a leak is occurring, but suggest i replace the entire fuel system from fuel tank to engine.
Problem is, this part(F1V49l291A) is both the fuel AND the brakelines bundled together, AND it's Can $901.68.
More than that ...to replace it ....the body has to be removed from the frame, to do the job, AND it takes 12 hours at $80 per hr to do it.
total cost is over $2000 ! and i only paid $5000
for the car.
Has anyone ever heard of this ?
My question is... is there another way of doing this that could be just as effective ?
for example :
The mechanic did say that it's standard fuel line and COULD be formed around the under-body to replace the suspected leak area, by cutting out the line from where it comes out from the firewall to the tank, and patching in a new piece.
A: That is probally your best bet, cut out the old rotten peice and join in a new line where the old one is'nt so rotten. Or just replace the whole line.

Q: Hi, my name is Kim and my 1989 Lincoln Towncar Limousine rear air shocks fill up when started but immediately they go down.
What could be the problem?
I was told by the Lincoln dealer that the air control module isn't working and needs to be replaced. I am not sure if I am being taken for a ride on this.
P.S. Once when I was driving the limo, I heard what sounded like a piece of material ripping. What could that have been? The air shocks have never worked since we bought the car second hand 2 years ago. Hope you can help. Thank you!
A: If the shocks hold the air being pumped into them, then it is on the controls side that the problem is being caused....
You need to find a trusted mechanic to check this.... Ed
Q: My Lincoln has been running a really rich fuel mixture. It's got the 5.0L with TBI. I checked the codes and found a code 41 "EGO not switching, lean exhaust bank 1."
Well I tested the O2 sensor and sure enough it was bad, reading steady .1v. I replaced the O2 sensor and cleared the codes. Checked again and got same code, and engine still running rich. Checked the O2 sensor and it was reading about .7v - .8v, a rish fuel mixture. I hooked up an emissions sniffer to the tail pipe and it calculated the mixture to be 10.5:1, way off from a 14.7:1 perfect ratio.
I found a Ford 'H' manual and followed some pinpoint tests using a breakout box for the ECM and found wiring to be ok, no excessive resistance in O2 circuit or fuel injector circuits.
I've run this Sun Carbon-Clean System through it which cleans the injectors, valves, and combustion chambers.
I've sprayed some carb-cleaner around the base of the throttle body and intake manifold and the vacuum lines in search of vacuum leaks but never noticed any change in idle-no vacuum leaks found.
The engine also has a slightly rough idle, probably because of the extremely rich fuel mixture. Tested fuel pressure and it maintains 38psi. Tested EGR valve operation and it seems to be functioning ok, not stuck open and opens fine when vacuum applied.
Other than the slightly rough idle, it seems to run ok, just has poor fuel economy. This has been driving me crazy trying to figure this out. Can you help??
A: Have you unplugged vacuum hose to fuel pressure regulator? Is it leaking?

Q: Hey what's up man, well here we go all I need to know is where the ground is for the pcm.. I was coming home and it quit..No sounds no nothin, and I had it fixed the first time and they said it was the pcm ground. They fixed it and that was it...No Injector pulse spark or anything...So This is what I am going to try first..Thanks
A: well bill,
your PCM is located under your driver side door panel. To access the pcm port just take off a few screws and take a tire iron and pry the door away from the interior. Once you've gotten into the PCM pull it our and replace it.... from there on you put your car back together and go bumpin on down the road .. bump bump bum bum bum bum bump bump... yeah.
