You get new vehicles like Almelda Marcos gets new shoes !!
1st try calling Ralph the exorcist to rid the truck of all aparitions,
spooks, and gobblins. Then grab your FSM and DVOM and start digging :)
Check the easy stuff 1st, injectors (noid light??). You said the IAT works,
but have you checked to see if it's carboned up, maybe some varnish is
making it stick when cold??
I may not be an expert, but I can sho nuff piss in the wind with the best of
em :)

-Ok, if everyone remembers, my friends 97 V-6 automatice Dakota 4x2has been
-acting up in the past. His performance mods are as follows: Flowmaster 40
-series split into dual 2-1/4" exhuast, Mesa high flow cat, K&N FIPK, had a
-JET chip but it is not installed at the time, Autolite 3923's, MSD 8.5mm
-wires, Borg Warner brass cap&rotor, 180 thermostat, MSD 6A with MSD tach
-adapt pn 8910 (the MSD was throwing a code 43, according to MSD
-some Dodges
-do it and some don't. It no longer gives that code since the tach adapter
-was installed at MSD's recommendations.). Ok, what his truck is doing is
-after being cranked the first time after sitting over night, it
-does fine.
-Let it run about 3 minutes and turn it off. For the rest of the
-day, (unless
-it sits like 5 hours) when he cranks it up, it revs to ~800 -
-~1000 rpm and
-then fall on its face dead. The only way he can keep it running is to
-feather the gas and slowly ease off until it stays running.
-Sometimes that
-requires him holding the gas down and keeping the motor @~900 rpm
-and putting
-it in drive. Once he is rolling and can get down on it, it will
-stay running
-fairly well till it smoothes out. Oh yeah, the engine is throwing
-no codes
-either and the check engine light does nothing while this happens.
- Here is a
-list of what we have replaced (in order): 1)did a complete tune up
-(hence the
-new performance wires, plugs, etc...) - did no good. 2)Crank
-position sensor
-(trying to solve the code 43) - no good 3)TPS - did nothing 4)Camshaft
-Position Sensor (aka pick-up coil in distributor) - did a little
-good 5)MAP
-sensor - helped getting the cranking rpm up to 1K. At this point,
-it would
-still die upon cranking. We put a fuel pressure gauge on it hoping it was
-the fuel pump. The fuel pressure remained rock steady, even during the
-engine dieing at 48 psi. So we took it to the Dodge place and
-asked them to
-scan the computer for codes and check sensors. Of course the damn thing
-wouldn't act up there, kinda like a little kid at the Doctor's office!!
-Pissed us off!! The dealer hooked it up anyway, and said it was throwing
-some weird codes, codes that apply to the V-10 (no. 9 injector not firing,
-primary side of second coil dead, etc...), but the codes wouldn't
-show up on
-the Dash. Go figure. Ok, so we swap in a new computer. This is
-what really
-pissed us off, didn't do a DAMN thing. And of course since it is
-electronic,
-Dodge won't take it back!!! So now we are stuck with a new computer that
-ain't worth anything but a back-up paper weight. Any ideas? The only
-sensors we can think of replacing anymore are the coolant temp sensor, the
-air intake temp sensor. We thought about the IAC, but if we take
-off the K&N
-fipk, we can hear that thing sucking in massive amounts of air. That and
-once we have it running, you can click on the a/c and hear the iac
-cycle on
-and off with the compressor. The o2 sensors were replaced about
-5,000 miles
-ago, so we think they should be ok. What else can anyone think
-of? We have
-tried bypassing the MSD and reseting the computer. No good, works for one
-crank, then back to falling on its face. Any ideas? We are
-shooting in the
-dark now, pissing in the wind, trying to pee in the toilet with the lights
-off, scratching our heads, scratching our butts, piling beer cans
-up into a
-pyramid just to have something to do, unplugging things and
-re-plugging them
-to make it look like we know what we are doing, scratching other
-parts that I
-can't mention, and then finally giving up. We would take it to a
-dealership
-up here, but they told us they want $118 to hook it up to the scan machine
-for the first hour (doesn't matter if they do it for 5 minutes or 1 hour,
-they charge us for one hour) and then $55 an hour after that to keep using
-the machine. If they have to trace down the electronic problem with a
-volt/ohm meter, they want $80 an hour. That kinda floored me.
-But they are
-the only shop around here I trust. I would do it, but I don't
-feel like it,
-not with all the other projects I have going on. This sucks.
-Help, please!!!
-TIA
