Error Codes

Car Information:
Ford F-150
Year: 1995
Engine Size: 5.0L
Trans: Automatic

Issue/Question: I pulled out three codes that are 172-173-327 and nobody can tell me what’s wrong with it I cant figure it out can you tell me what’s wrong with it and what I need to do to fix it cause its driving me crazy the only think I can do is take the wheels off and attach another truck on them, thanks john

Answer:
Without looking at the data from our NGS tester theirs no way to pin point the cause of these codes it would be a shot in the dark. This year truck did not have data ability for a technician to look at for anything other then the NGS scan tool.

Vibration

Car Information:
Ford F-150
Year: 2005
Engine Size: 4.6L
Trans: Automatic

Issue/Question:
Installed new brake pads, new calipers and new front disk. Also wheel alignment done after break jobs. It has a bad vibration at the front end, sometimes it disappears but it comes back after a short drive around the block ( Also, all four quality new tires).

Answer:
Next time your in Orlando stop by and let me drive it, It may be a worn tail shaft bushing in the transmission causing excessive play in the drive shaft and causing the vibration, this is very common on 2004 and newer F-150’s

Transmission Chatter/Shutter

Car Information:

Issue/Problem:
I’m driving @ 55mph and slow to @ 20mph when I accelerate the transmission chatters/shutters twice then is fine. This happens only periodically, maybe once evey one or two hunderd miles or so. What is the likely cause and solution?

Answer:
Glazed clutch’s, Ford recommended Amsoil ATF and an additive called Smart Lube it helped de glaze the clutch’s.

High Idle

Car Information:
Ford F150
Year: 1994
Engine Size: 5.8L
Trans: Automatic

Issue / Question:
High idle – changed the IAC valve three times, the last time I scraped and vacuumed out the carbon. Each time it runs great for 2-3 days, then the idle revs up really high. I turn the truck off, wait for a minute, and then turn it back on and it runs fine for a few minutes then idles high again.

Answer:
It sounds like the ISC is trying to compensate for an intermittent vacuum leak. Its possible that the EGR valve is sticking open for carbon.

Ford F150 Transmission

Car Information:
Ford F150
Year: 2004
Engine Size: 5.4
Trans: Automatic

Issue / Question:
I have a hard bumping at around 42 mph and again at 58 mph. It seems to only happen at slow to medium accelerations. If I accelerate through these speeds quickly it seems to go smooth. At such consistent mph/occurrences, it leads me to believe it may be a trany issue. Is there diagnostics you can do on these newer transmissions? It so what is the cost and what will it tell me. I just had the fuel filter changed and the transmission pan dropped about 10K ago. Truck has approx 120K.

Answer:
We need to drive it, as it sounds like a torque converter shudder. If that’s the case Amsoil ATF and Smart Lube modifier may be the answer. The worst case is replacing the torque converter.

Blown Fuse in Ford F150

Car Information:
Ford F150 HD Pickup
Year: 2002
Engine Size: 5.4
Trans: Automatic

Issue / Question:
5 amp fuse on interior fuse panel (#15?) blows immediately. Short to ground can’t be found. I think fuse is for RABS, GEM Module? Inop items are interior lights, seat belt reminder, wipers, horn, electric windows, and will not shift out of park after engine started. Any idea where to look? Have checked wiring on frame, engine compartment, firewall plug connection, isolated brake light on/off switch, Transmission Range switch, drivers door panel electric window rocker switches, wiring on lower door sill under carpet checked. Have seen this problem before?

Answer:
Maybe a door latch switch! Seen the switch go bad and cause it to short out and blow fuse when you shut the (most likely the drivers door).
Try a 10 amp fuse if history repeats itself I would pull the door panel and look at the drivers door latch switch.

Ford Super Crew Transmission Chugging

Car Information:
Ford Super Crew
Year: 2004
Engine Size: 5.4L
Trans: Automatic

Issue / Question:
I missed a transmission service at 90k miles and started experiencing chugging between gears at 1500 rpm at 45 mph. At about 125k miles I got the super duper transmission service and the chugging is still there. Is there a way to tell if I need a new transmission or could it be something else?

Answer:
What your describing is the transmission is going into 4th gear or torque converter lock up at too low of an RPM causing a chugging sensation! Alright if this is the case I would scan the computer system first to make sure the vehicle speed sensor is fine. If there are no codes I would be inclined to reprogram your computer if necessary, to have it shift later by 5 to 7 mph. I will have to check, there might be an update on this. If not, we can program a different tire size to change the shift pattern; bottom line is if it’s a shift timing problem we should be able to save the transmission. However, if it’s slipping already, it may be too late to save it. A test drive will let us know what to do.

Ford F150 Fuel Guage does not work

Car Information:
Ford F150 4×4
Year: 1992
Engine Size: 4.9 6 Cyl
Trans: Automatic

Issue / Question:
Fuel Gauge will not work. It goes past full and stays there. Have replaced the pump and dash gauge to no avail. Would like some idea on where to go from here. Thank You.

Answer:
Sounds like the fuel sending wire is grounded out somewhere between the sending unit and the gauge. Try running a new wire temporary just to see it that’s it.
