Hope this is the right forum.
I've about had it with my '94 Ranger. Issues since day one. Imagine the following scenario:
You're driving down the highway on your way to work doing 55-60mph in 5th gear on a LEVEL section. Everything is fine. Then, all of a sudden the truck's speed starts dropping off and feels a bit rough. You give it more gas. Nothing. Truck is doing about 45mph and the RPM's are not changing. You drop to 4th gear and apply the throttle. No change. Nothing! RPMS will barely change even w/ the gear change!
At this point you have 2 options:
1. Ride out this tantrum and eventually the engine power will surge back to where it should be. Truck starts driving normal again (until it decides to have another tantrum).
2. Drop to 3rd gear and mash the gas pedal. Now the truck will start gaining power and speed, a bit rough I might add.
After choosing one of the above options, the truck will run as it ought to; like nothing was ever wrong, till it decides to do it again.
1994 Ranger S/C 4x4; 4.0L/5spd.; 3.73LS rear/31x10.5x15; 265/75/R15 Stock tire size.
What have I done (within the last 2K miles):
Cleaned MAF
Cleaned IAC, then replaced w/ new one, no change, put old one back on.
New Fuel Filter
New TPS, voltage test seemed to indicate it was faulty
New PCV valve
New air filter
New Motorcaft upper and lower intake gaskets
New Felpro Permadry Plus VC gaskets
New Thermostat, old was was stuck open
New ECT, did this for good measure while intake was off
Check resistence in coil pack; seemed fine
Ran 2 cans of seafoam thru engine
*New Motorcraft Plugs and Wires after seafoam flush
New Clutch and Slave Cylinder, Old Pressure plate had collapsed fingers
Replaced fluids in tranny and rear end
I have 2 codes:
327 EGR circuit below min voltage (is this a DPFE issue or EGR solenoid)
*172 O2 Bank 1 Lean (could code 327 possibly throw this?)
Is it possible for either of these two codes to cause the symtoms I have?
* Prior to replacing the plugs and wires, the truck had fairly new plugs and wires (cheap ones) on it. The truck was giving me fits as described and I came to find out the wires didn't seat properly in the coil pack. Replaced with Motorcraft wires and plugs. Truck ran MUCH better. Symtoms desrcibed were gone. Now they're back?
The plugs that were in the truck were Autolite copper cores. Plugs from EVERY single cylinder looked good. No signs at all of a lean condition in bank 1, which makes me wonder about the O2 code.
When the clutch was being replaced at the garage we ran into a problem. The truck refused to start. It would crank all day long, but would not fire. We had spark, fuel, and a grocery lish of codes. Came to find out there was a bad ground. Fixed that and it fired right up. All but the above codes went away. At this time we also checked the FPR (good) as well as the rail pressure. I don't remember what it exactly was, but it was with in spec (~35psi IIRC). After the truck was shut down, the fuel psi held at ~40 psi.
Also, I recently took a 200+ mile trip in the truck. 98% was all highway driving at speeds ranging from 45mph (construction zone) to 65mph. The truck only managed ~16.5mpg (usually ~15mpg Highway!). How anyone is getting 18-20+mpg is beyond me.
Could I have a fuel pump on its way out? This problem is intermitent, but happens several times on my 30 mile drive to work.
I am out of Ideas and $$$. I just want this truck to run the way it should. Sorry for the novel I just wrote. Any help or would be greatly appreciated. Thanks!
