Not sure about the postion of the missing teeht and valve timing

Pedal Relearn Procedure
Accerlerator Pedal Released Postion Learning is and operation to learn the full released postions of the accerlerator pedal by monitoring the accelerator pedal sensor output signal. It must be performed each time harness connector of accelearator pedal postion sensor or ECM is disconnected.

1. Make Sure the acceleartor Pedal is fully released
2. Turn Ignition switchON and wait at least 2 Seconds.
3. Turn ignition switchOFF and wait at least 10 Seconds
4. Turn Ignition switchON and wait at least 2 seconds.
5. Turn Ignition switchoff and wait at least 10 seconds

Throttle Valve Relearn
Throttle ValveClosed Postion Learning is to learn the fully closed postion of the throttle valveby monitoring the throttle position sensor output signal. It must be performed each time harness of
electric throttle control actuator or ECM is disconnect.

1.Make sure accelerator pedal is fully released.
2. Turn ignition ON
3. Turn igntion switch OFF and wait at least 10 seconds. Make sure that the throttle valvemoves during the 10 seconds by confrming the operating sound.
(You can hear the TB sound when you have key on and shifter in first gear and step on the gas. So you know what you listening for.)


Idle Air Volume Relearn Procedure
The Following Condtions Must be met in order for procedure to Work.

Battery Voltage :More than 12.9 volts at idle
Engine Coolant Temp 158-203 degrees Farenhiet
Electric Load Switch OFF i.e Air Condition, headlamps , rear defogger
Steering Wheel: Neutral Postion (Straight Ahead)
PNP Switch: OFF (Park Neutral Switch i.e. Clutch Switch...pretty sure)


1. Perform ACCERLEARATOR PEDAL RELEASED POSTIONS LEARNING
2. Perform THROTTLE VALVECLOSED POSITION LEARNING
3. Start engine and warm it up to operation temperature
4. Turn igniton switch OFF and wait at least 10 seconds
5. Confirm Gas Pedalif fully realeased, then turn igniton switch ON and wait 3 seconds
6. Fully step on and release gas pedal5 time within 5 seconds
8. Wait 7 seconds and fully step on gas and stay on until MIL stops blinking and is steady.
9. Fully release the Gas pedalwithin 3 seconds after the MIL has turned ON steady.
10. Start engine imediatly and let idle. Wait 20 seconds.

think its time to remove the head and renew the gasket ,also remove the valves and renew the seals and gring them in a bit ,maybe even renew the valve springs ,or buy a newer vehicle as its nearly 20 yrs old

i belive its the crankshaft postion sensor try replacing that

I haven't played with too many diesels,but many cause of a miss are similar.If it doesn't miss all the time,then I think you can rule out a compression problem(at least as far as rings/piston/cylinder).You could have a valve sticking,or maybe a plugged injector.Not sure of a good way to figure out which cylinder is missing,maybe someone else could give you an answer to this on here.(You could check for a sticking valve by running it with the valve cover off,I suppose).

Some times junkyards can be your best resources for cheap parts. However I do not recommend some parts purchase from a junk yard.

not sure about timing. whaddya mean not sure? remove distributor cap. have someone crank it. if the rotor in the distributor isn't turning, you've got a busted timing belt, maybe bent valves, i'm not sure if it's a non-interference engine. Timing belt $800. bent valves=new car.

What engine? Sounds like maybe timing chain jumped or it is very lean.

as soon as I got down here the bike started dying about 15 to 20 minutes into a ride. This bike has never given me a single problem prior to moving. It seems like something electrical to me but I really have no idea where to begin. I'm guessing (wild shot in the air here) that some component is getting hot and failing. I could walk downstairs and start it up now and it would start fine and then fifteen minutes later it will die and not start until it has cooled down and sat for a bit. This has happened four times now. I keep it in the neighborhood since I am expecting it to shut down and I end up pushing it home. I've drained the gas and replaced it checked all of the connectors I could get my hands onto. I had some crud on the positive terminal that I could see glowing, so I cleaned all of that up. I'm planning to tear the engine down soon anyways, but I'd like to know what is causing this before I get started. If anyone has experienced this, I would appreciate any info. Thanks guys. Relevant Info: 1998 748 ~20k miles Sil 1/2 system, ITG filter, DP chip,You're throwing darts instead of troubleshooting. When the bike is dead, begin the diagnosis by determining which of the three required elements are missing; i.e., air, gas, or spark. Once you determine this, then systematically trace upstream from the engine, using a good shop manual which describes the systems. Most manuals, like Haynes or Clymers, have a troubleshooting section which may help you once the missing element is identified.,,,
