i did a fresh top end/tranny build on my 2g dsm threw her all back together last month and ive been driving around with an R plate till i made sure she can handle a nice long drive. so i got her up to snuff and took her out to hope and back and it was pretty nice being able to be in that car on the highway again , damn does it ever cruise nice... but anyways to the point.
heres where im going to get technical:
on the 5 gas at idle (750 +/-50 rpm)
Co2 12.3%
Co 0.08 %
Hc 125ppm (+/- 50)
O2 4%!
NOx 26ppm
Snap Throttle>>
Co2 5%
HC 3100ppm
CO 9%
O2 10%
Nox 80ppm
hooooooooooooooly cow eh so first im running super f'in lean at idle, then when snap throttle comes around nothing gets ignited!
frankly i dont know how my car is even running with numbers like these.
So what ive checked thus far:
!CMP,CKP: Both look okay when scoped side by side with my Verus however, when the CMP sensor is scoped solo it produces a 5v ref signal for well over 75ms which is the only thing alarming ive found between the two. but not enough for me to say "hey thats not right"
!ICM: the module was tested and i have 45,000Ohms between pin 3 and 7 , 1 and 3 or whatever the other continuity check is, so i figured oh dang thats pretty high resistance but according to chrysler, forget it, there shouldnt be any connection between the two. so i get a replacement from westcan and im getting the same reading, so see ya later sent it back.
!Coil Primary and Secondary: This is weird, the first time i did a basic resistance test on the primary side my reading were astronomical 2.5 ohms on the 1-4 coil and 1.9 ohms on the 2-3 coil, so rather then just replace the coils i pulled the bracket out with the coils check for high resistance in the wires from the connector to the coilpacks and everything was within .4 ohms, a little higher than i wanted but still okay. So i did another resistance test on the primary side just to be sure and god damnit it showing me .8 ohms on both...what the ....... so whatever put it back together double checked my values and yup its apparently good. secondary system consist of BPR6ES and new NGK wires just replaced for warranty. still same issue.
then i went ahead and scoped the firing line and really nothing jumps out at me. the firing line is pretty much spot on when it comes to comparing it to other waste spark systems.
!Timing: now being a 2g i know there is no adjustments i can do since the car is pretty much stock. BUUUUT heres the weeeeeiiirrrdd part which can indicate a specific problem that i havent been able to find yet. the timing light, when connected to #1 plug displaying the rpm will vary between the actual rpm of the engine then up to number like 1600 rpm, it will actually fluctuate on two cylinders mainly 1 and 3 both the waste side of the coils up and down , up and down up and down. never really finding it true spot. my grounds everywhere on the motor are good.
loaded up on the PID display STFT is showing me -1.6 to 0.8 LTFT is showing me -10.8 MAF is reading around 3.33 g/s. unfortunately there is no PID available for the MAP but i still have to scope the bastard out.
when it idles you can defiantly feel a shake but nothing outstanding nor can you feel anything crazy when you drive her especially when you hit the boost but i defiantly know there is a lack of power (2nd gear has no punch). there is no dtc's other than p1104 p1105 but those are sensors ive disconnected , it doesnt ping it doesnt surge it doesnt give you any indication that its running pretty damn shitty. and what really bugs me is at idle when the NOx are so low so is my CO. lean mixture +NOx a rich Mixture -NOx and my O2 is just way way way too high. im almost starting to think my 5 gas machine is hooped.
Now looking at the aircare history this car has failed about 10 times, maybe 8 fails until it finally passed and i bought it without knowing, "hey maybe i should check the history". Whatever they did to make it pass was a bandaid fix more than likely a new big body cat to soak up as much shit as possible with a good combo of methyl hydrate.
Going thru aircare my HC and CO absolute soil the bed with hc being at 1.5ppm and co being at 15% !!
so since im beginning to find that there is quite alot of silly things that get over looked on this car that can cause some major issues, i need your opinions and dsm expertise
thanks boys/girls
