More Ideas? Keith as to the shimmy check your front wheel lugs. Can't think of anything else we pulled apart yesterday that would be related. Glad you got home fine.

yeh I think Rich was torquing them to speck, I dunno if he did both sides.

I'll check

edit wheels were tight. will keep an eye on it. as for CEL, I'm going to leave it on for a while. I'm going to go watch the leafs.

GO LEAFS GO!!

Don't forget you are suposed to retorqe them after 100 kms or so.

From my manual.


-- HO2S-11 = DTCs P1131, P1132 and P1130
-- HO2S-21 = DTCs P1151, P1152 and P1150
Possible causes:

Fuel system
-- Excessive fuel pressure.
-- Leaking fuel injector(s).
-- Leaking fuel pressure regulator.
-- Low fuel pressure.
-- Contaminated injector(s)

Induction system
-- Air leaks after the MAF.
-- Vacuum leaks.
-- Restricted air inlet. don't think so now!
-- PCV system.
-- Fuel purge system.
-- Improperly seated dip stick. WTF!

EGR

-- Leaking gasket.
-- Stuck open EGR valve.
-- Leaking diaphragm.

Base engine

-- Oil overfill.
-- Cam timing.
-- Cylinder compression.
-- Exhaust leaks before or near the HO2Ss.

l Check air intake for leaks, obstructions and damage.

l Check air filter, air filter housing for blockage.

l Verify integrity of the PCV system.

l Check for vacuum leaks.

Fuel system
-- Excessive fuel pressure.
-- Leaking fuel injector(s).
-- Leaking fuel pressure regulator.

Computer still calibrated to thinking the CNG is still there. Now it reads a value wrong and throws this code. What we need here is to find the other computer from the install (there was one right?) or swap his computer with yours Jeff to see if it drops the cel. I'm really leaning towards a programming issue now. Nothing is different from a stock set up now from what I can tell at this point. Is that agreeable?

I'm game if you wanna try my comp. I got a spare we can test with, but I won't sell it.
I got a comp from a wreckers for $70.

ok new news...

after the game I drove home.

well I cleaned the engine today, and then went to a buddies to watch the game. no problems..

on my home from the game I noticed that the car is now hesitating.

when I jam the gas it goes fine. but when I slowly accel it hesitats until about 3500..

I'm going to reset the computer and see if it does it still..

Both hesitation and the codes go together with vacuum leaks. I'm a little tired to think well now, but maybe someone can think of eliminating some possible causes that also require to have other symptoms. Am I making sense?

not any better. and its still consistant with the drive for 15km, shut off, start up and 2 km in CEL comes on..

the damn car runs like piss. when sitting idle, the rpms are like @ 500 and it is just chugging, sounding like its gonna stall. I'm not sure what the air intake is supposed to sound like, I hear a hissing where the filter is when just idling.

I've had enough for tonight, gnite and talk to you tomorrow.
