Engine Performance problem
1999 Chevy Tahoe V8 Four Wheel Drive Automatic 190000 miles
99 Tahoe - 190k mil. Issue =
For the note its getting worse.
The effects -
Lose of power / Choaking / Baby back fires if I try to put the gas on. I have noticed iv lost major power anyways
from this v8 now then when I bought it (used)
Before (Cold start) No issues. Until the truck worms up after 1 hour? Driving, if I push the gas in to go hard, it has this BAM no power. Nothing. IF I force the gas in even when I know im getting 0 power out of it, (feels like it goes into neutral) it has baby back fires. When I let off the gas, push in 20% it has some what enough power to drive down the street. So when I take off, or even go anywhere, I can not push the gas in much or it will just choke.
Only way I figured out how to fix its self (Before) was
to just shut it off for few minutes. Then I found out I can I shut it off for 5 seconds until computer resets and re start it - (before) I got power and no choking.
But now, even after 2 hours of driving, rebooting (shutting off) does not help 50/50 of the time.
Its getting worse after 2 weeks now?
Prior to this happening, I used to drive only in 3rd.
Then I started to just drive in (D). Started to have check light come on. Then it goes off. Second time it came on got it checked out. O2 Position 1 and 2 censer is bad. Then light goes back off. Only 3 times this has came on, no I haven't changed them.
No, I have not did a tune up, or changed anything.
Not put any fuel cleaner in or nothing.
