GM techs... not sure what the hell is going on.

Copied from my GTO forum, I don't feel like typing oit out again.


So today I was doing maintenance, brakes, and axle back exhaust.

Maintenance included: Svede K&N filter charge, engine oil, trans fluid, rear end fluid, power steering fluid, and brake fluid.

Goodies were a complete brake upgrade, and Kooks afterburners.... not related

So I naturally started the car with the MAF unplugged while I was checking the trans fluid level. I turn it off right away. Plug it back in and it still started like a bitch and settled out. Check engine light was on at this point. Crud, I'll just clear the code later.

I'm going to go out to bed the brakes and get some MAF cleaner. I cleared the codes. Still started like a mofo. The instant I shifted into reverse I knew something was up here now too. It really torqued up when in reverse. Part throttle it is S L A M I N G gears. I have a CW TCM, but something was really different. I read a thread on here that stated the same trans issues I have and it was due to the P010X codes.

MAF cleaner didn't do anything and I still get codes.
I have the following codes:
P0101, P0102, P0103, P0335



Also...
Kooks are AWESOME under bridges, a little loud for my tastes but I'm sure I'll get used to them.

Disconnect the battery and clear codes

Been clearing the codes with my hand held. They go away and then come back.

So you have 3 Mar codes and a crank sensor code..... re-check all your connections. I doubt you fried anything startinig it up without the MAF. The reason your trans shifts different is because of the MAF stuff, I'd guarantee it.

i have a vac gauge two screw drivers and a timing light and some jets...... want me to fix it

The only code that doesn't fit with the others is the CPS code. Check your harness. IIRC, the MAF and CPS are fed from the same hot circuit, right?

Heh, we were just talking about carbs today....... old and tired just like me

I'll have to check everything again on Saturday. I've been so damn busy lately with "things" and today was my day to get car stuff done. I flippin love the brakes and noise makers though.

For whatever reason CPS gets tied into the other codes I think...


CONDITIONS FOR RUNNING THE DTC

* DTCs P0101, P0102, P0103, P0341, P0342, or P0343 are not set.
* The camshaft position (CMP) sensor signal is incrementing.
* The mass air flow (MAF) is more than 5 g/s .
* The engine is cranking or running.
* DTC P0335 runs continuously when the above conditions are met.

Check your fuses

^ I checked the engine compartment ones already. One mentioned the O2 sensors are tied into the same circuit (By the trans pan...). Keep 'em coming.

I just found my new sig

Uh.... okay. In a lot of GM vehicles with auto trans, if a fault appears in the MAF circuit, I've been lead to beloved the pcm can command the trans to either shift different, or sometimes not at all. This is on electronically controlled autos ..... am I wrong?

http://www.samarins.com/glossary/airflow_sensor.html. so it looks like I could be right.... Is the GTOs pcm using MAF data to shift the trans? Idk.

He is right from what I've briefly read, at least with my model of TCM & ECU.

Top news, detective blackout comes through again.

LOL

Little known fact: I actually hold a Private Investigators License in the State of Wisconsin. No Joke.

Bro...I could use your help. I have an apartment building and want to serve some people that owe me money and don't have any idea where they are.....
Calll me 575-1641 or email

If you are serious, yeah, I can help with that!

yup....call me

hahah this thread delivers!

Detective Blackout.... A real life Superhero

kind of

Its not funny because I think your wrong its funny because blackout is "guarantee-ing" how to fix a problem. I just find it funny

Even boner head can get his money back on that guarantee

Why you got to drag me in to this?

So you do answer to that name? ^
