Code 44 indicates a lean mixture at the oxygen sensor and it could be a variety of things from a vacuum leak, a bad fuel regulator, or a bad fuel pump. Also those engines were known for bad distributor shafts. It is best to take it to a mechanic.
Oxygen sensor stuck lean.
i have a code 12 on my chevy astro van what it means
Its on the front of the engine, next to the thermostat housing. On a TBI (throttle body injection, engine code Z) motor, it points straight up, on a MFI (multiport injection, engine code W) motor it points forward.
The Vortec is the GM 4.3L VIN Code "W" engine, the X is the non-Vortec
Yes they are Vortech is the heads and the intake the rest is the same
code 15 is coolant temperature circuit {low temperature} Im also trying to source exactly what this problem equates too as im currently trying to help a friend with the same code problem on his 1994 astro awd !
look at the vin# and it will be the 8th digit hope this helps and should be a letter not a number. on my 98' it is a R.
multiple random misfire on 4.3 vortec why?
What mean the code troble 1476.8 VW jetta 1994 engine 2.0
I can not without the manual in front of me remember which position its in but it should be either a 'W' or 'X' code, more likely the 'W' since 95% were made of this type engine, 262 CI / V6
how many fuel injectors in a 2003 4.3 v6 vortec x code
Code 41 Throttle position circuit fault
