hesitation / fuel filter? tpms - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I have a few weird issues.. 1. My service tire pressure monitor system needs servicing message comes on occasionally and either both back tires or usually passenger side rear show -- instead of pressure. They had thd car 3 damn weeks and said they replaved the sensors but 5 miles later after picking it up at stonebriar in Frisco tx it came back. I dont want to bring it back right now after driving a slow loaner for nearly a month i am glad yo have it back..

2. Sometimes it wont break traction and seems to be starved of fuel or air when i get on it.. boggs.. then takes off like a bat out of hell. It did have abs and service stabilitrack light on too but those are fixed so far since it went to shop a month ago. Chevy Dealer said it was my Maf intermittent coms. and replaced that too Along with my o2 sensors. it ran OK for a week but still does this occasionally (bogs down) I am going to see if its the fuel filter when it stops raining.. or injectors? Pump?

my car is a 2010 M6 LS3 with CAI with 45k its awesome 90% of the time but occasionally even with fuse pull and all nannys off it usually does this when the tpms light is on but not always.. could the Computer seeing tire pressure issues cause it to have weak throttle response like this? Or likely not and maybe fuel filter or pump even though its only 45k? I have always have used 93 octane and put new irridium ix plugs as well (better power seems like since plugs when its running good). It also did this before the CAI. I don't want to trust Stonebriar because 3 weeks of a Chevy Cruz loaner with no cruise control(no kidding) sucked. I can't afford to do a resonator delete just yet to open up the exhaust. I can run 4.105 to 4.7 0-60 when she's running right and no codes but when she's not I only do 6 second 0-60 and that's all because of the first 60 ft of hesitation. I am confident its not pushrod or anything too serious because it comes and goes. Usually fine and awesome... any ideas?

Thonk ot may be this TSB.. "Some customers may comment on an intermittent engine hesitation or flutter.
This condition may be caused by the intake camshaft position (CMP) sensor bank 1 connector
terminals having intermittent conditions or poor connections. This will result in the engine control
module (ECM) temporarily being unable to determine engine position and it will stop fueling and
sparking. The ECM will require at least one engine revolution to resynchronize (resync) and if it
does, it will not set a DTC.

Man.... that was a tough read.

No fuel filter that is changeable on these. The fuel pump module has a strainer but thats about it. What other, if any, codes are you getting?

texsean · 05-12-2015, 04:51 PM

No other codes. None since I replaced the plastic vaccuum line either and I relearned the tpms by walking around and letting out a pound of air per honk and that problem is gone now too. The car is running great last few days so cross fingers... oh sorry for all the typos. Life's too short to fix them all. Lol

One thing I did notice was the o2 live readings are way different on sensor 1 than 2. Sensor 2 barely moves when I Rev the engine but sensor 1 jumps down on graph when I Rev and back to middle of graph.. idk what that means. Guess I'll Google it
