you could try spraying small amounts of engine start spray near intake connections and see if rpm rises from idle. Just be carefull to to get it on hot exhaust else flash fire.

should rearly be covered by repair shop under insurance or a warantee claim especially since your car is stock

Ok i will do that tomorrow and will let you know how it goes thanks

So I got around to spraying every tube that leads to the intank even brake booster but nothing no shake no hesitation. So now I'm left guessing it the oxygen sensor what are your thoughts???? Oh and I drench the area around the maf sensor

Mate, I would hate to see you start replacing expensive bits on speculation. This is where you need diagnosic tool or logging devices to log whats going on in ecu. Else you could end up replacing 02 sensors when its the maf sensor or its an exhaust leak ect. even with correct diagnositcs its difficult to pin down this sort of thing, it can even be bad fuel.

Probably time to take it to a shop dealer or get the insurance company to fix.

Yup dealer becuase this Sucks thanks pal I appreciate your help

Ok so my o2 sensor reads 0.0 when oof the gas and jumps up to. 0.8 the highest cell still comes back on the bad part I can't get a reading for the air fuel ratio sensor

When you off the throttle injectors shut off completly to will read full lean, looks like your reading sensor volts not afr.

So would it be my oxygen sensor or o2 sensor becuase it's reading 0.0 volts when off the gas now I can't get no reason from air fuel ratio sensor because torque isn't compatible with that's reading?

[Albaro08]

Ok so what I've noticed when I get into the 3-4 rpms were the car hesitates the timing drops from like 46 instantly to 31

thats probably pretty normal as rpm and load increases timing decreases

[Albaro08]

So if it increases which does when I'm going faster at times might that indicate it's probably most likely air sensor before I take to the dealer just want them go straight to that and even if I can do it myself and change it I appreciate your feedback alot

Ignition timing will vary with load,throttle position rpm ect their are heaps of maps in play you need to log a lot of inputs to see whats going on.

have a look at your long term fuel trims LTFT across the rpm band, it will change but high fuel trims in lower rpm bands like 10% can indicate intake\exhaust leaks

[Albaro08]

Ok just saw that right now going 78 and the trim went down do 3% so idk I'll keep checking but i have a got feeling it can be the air ratio sensor

I found the culprit it's my headers it's leaking from an elbow something like white fussy paper type looking thing. On the passenger side changing the transmission oil today I looked into that and when it was gassed it blue out some air from there not alot but enough to call it a leak it's going in on Monday so they can find out what it is but I will tell then so they can get right into it.

Any leaks at header connections or 02 sensors will cause problems, the shop probably re used the old gaskets when they removed exhaust, reused gaskets always leak
