Bogging out 2-3k rpm
Bogging out 2-3k rpm (Updated) Any help appreciated.
Car is bogging out and it does worst when cold, usually happens from 2k-3k rpm, seems worst under load (when in gear vs. neutral).
I scanned today and got the codes below:
P0155
P0135
P0140
P0160
P1133
Dont all except for the P1133 pertain to the fact I no longer have rear 02s?
Ive been tryin to eliminate this problem and this is what has been replaced:
fuel filter
vacuum hose
spark plugs
plug wires
new Bosch 02s
No luck yet. I havent tested fuel pressure and how do you test injectors?
Please help. Mods listed on my sig.
Thanks!

Wow, all those codes?!?! It sounds like your O2's died....horribly.
Who tuned it?
BTW, not all of those codes refer to the rear O2's. Just the P0140 & P0160. The rest refer to the front sensors, which are responsible for fuel trim calculations.

txhorns281 tuned it. This was tunned a while back 2yrs ago and I didnt have a problem until maybe like 3 months ago.
So does a tune go bad? WTF is going on ?
FYI, 02s replaced yesterday and PC was reset.
Codes pulled 2hrs ago.

As I just tossed out in a different post, I figured it was heat related; maybe these Bosch parts had a stronger heater... Let me know what you ran into though so I can be on the lookout.
So he ran one stock O2 and one of the Bosch pieces? A nice secondary plus is that the leads are long enough to not need extensions with LTs (for those that didn't know).
I have always swapped them out as a pair (and recommended the same) as these things seems to drift with age rather than failing, unless it's a heater.

Update!
Cleared all codes, re scanned 02 codes disappeared, misfire code came up. Upon inspection of the plug wires.
1 wire was touching a LT, so I wrap tied it away and also another questionable one.
Cleared the codes again, the car is running way better!
I havent re scanned, but im sure a re tune wouldnt hurt.
