'97 Blazer takeoff (near stall)
#1
I had some codes pulled for me at the Autozone, it threw 7 of them. Three were for the O2 sensor being bad (This could be the main culprit) and the others were a 1-2 Solenoid, 2-3 Sol, and a 3-2 Sol and I don't remember the other one because they all got thrown away.
Basically what happens is I'll be slowing or stopping for a sign or light, and when I go for takeoff there is a noticable lag with a drop in RPM where it feels like she's about to stall out completely, but recovers and takes off normally and seems to run fine. This happened to me last week sometime and has gotten more persistant since.
What I'm thinking is the O2 sensor is sending the wrong information because it's bad- 3 separate codes involving it. The second problem could be the fuel pump. Over the winter I ran it with barely any gas almost all the time, now I run it at half or above at all times.
What I don't get is that it never had a problem when I lived in Maine, as far as this problem goes. It would run perfect and never hesitate. Now I live in Cincinnati and this problem seems to be getting more persistant with every week. I went to the store twice last night and it did this to me like three times. If anyone could enlighten me on the subject I'd really appreciate it!

Do a fuel pressure/leakdown test. Post the results.
62psi and after 10 min should be no less than 55psi.
And if you had the codes it showed and the order they came up in would be very helpful too.. The trans trouble codes can be a sign of the electronic ignition switch going bad has happened to me 2x now.
