RE: i have no clue 2 what is going on
The last link in the fuel system is the Fuel Pressure Regulator. There is a great writeup in the DIY section
on how you can check/replace it. That and the gas lines that go to the spider injector underneath the intake
are common failures that cause bogging/no power.

O2 sensor is in the exhaust pipe, pointed upwards, next to the tranny. Just behind the front wheel, iirc.
44 means lean exhaust detected - it could be the O2 sensor acting up or you really could have a lean condition.

CODE 44
Trouble Code 44 indicates that the O2 sensor is showing a persistently high exhaust oxygen content (lean), despite the efforts of the ECM to increase injector on-time (thus increasing fuel delivered). Integrator and BLM numbers may indicate > 128 by a substantial margin.
The conditions for setting this code are:
no Code 33 or Code 34 (MAF Error) present, and
the O2 sensor voltage remains below 250 mVolts, and
the ECM is in Closed Loop control, and
the above conditions exist for more than 50 seconds.
Typical causes for this code include:
1) O2 sensor defective or lead shorted
2) Lean injectors (dirty or blocked)
3) Water in fuel
4) Exhaust leaks upstream of O2 sensor
5) Fuel pressure or volume too low
6) MAF sensor reading lower airflow than is actually present
7) Vacuum leaks
8) Incorrect or poorly calibrated PROM

RE: i have no clue 2 what is going on
If you have a good scan tool available, have yourself or whomever check at cold startup the coolant sensor(SENSOR) that reports to the computer. I have had one or two of these in my lifetime where that was the issue and the results were exactly as you said. Keep in mind that there are two(2) coolant sensors...persase...one for the dash and one for the computer so...if you were to say that the dash reads correctly that does not pertain to what I'm stating. Probably not going to be lucky enough that this is going to be it but worth a try. But, you have to have a scan tool that reads this sensor or I guess you could pull it and ohm it out but much easier to scan it and have a look! JP
