I have a 1996 blazer LT 2wd and i have a hessitation when it is cold outside it will sometimes stall within a couple feet of driving then it wont do it anymore i was wondering if anybody has any suggestions on how to fix it?

 

Does the check engine light come on while driving?
Have you checked for DTC's, (Diagnostic Trouble Codes) in memory?
If so, what are they and what order were they retrieved?
Have you checked fuel pressure and leakdown?
If so, what were the readings?
Have you checked or replaced the fuel filter recently?
After the engine is at operating temperature, (200*F) what is the idle RPM?

 

yes the check engine light is on and i have checked it and all it says is basically a o2 sensor is bad (for some reason i cant keep good o2 sensors very long) and no i havn't checked the fuel pressure i should though and yes i have replaced the fuel filter about 1,500 miles ago and the Rpms r running about 1000 rpms

 

DTC's never tell you a specific part is bad. DTC's tell you what circuit malfunctioned, and the flow chart pinpoints the problem. What DTC's are/were you getting? Do you have a scan tool that will allow you to view short and long term fuel trims?

EDIT: You'll need to get readings for fuel pressure and leakdown. RPM is high, should be close to 600 RPM. We can deal with that later.

 

no i do not have a scan tool to view the short and log term fuel trims and as for the readings, i will have to get my buddy hook his up and c what it is for shure, and where can i get a scan tool for fuel trims?
