Here we go again!!

[twenty2]

About a month ago, I had a issue with a Bank 1 and Bank 2 code showing my gas was lean. Do you guys think I have a gasket leak coming from my intake manifold? Or, something else? The O2 sensors were going to be changed, but they say its kinda hard to beleive that both banks would go out at the same time?

Any help please.............

I Had the same thing happen about a month ago. I was told it was my MAF, so i cleaned it out(after market MAF) same thing happened again. I was thinking possibly the cats.I will hopefully be dropping off my truck again next week to have them look at it again. Its still under warranty. If i get the issue resolved I will let you know what the problem was with mine. Till then good luck.

do one of two things:
1)with engine running, pour bucket of water or run water hose over intake, esp at cyl heads to see if idle stumbles
2)spray carb cleaner or starting fluid around same area and see if idle raises.
either of these will point to leaking intake gaskets

Ill give it a shot...

I had issues with idle and cruising issues for awhile... I just replaced my freaking injectors and that solve my running lean issues... Then again I dont know if you guys have 80K in mileage on your rigs ????

I do.... hummm, too many things to either change or check...

This may not apply to the H2 but.....I have a 95 Neon that I pretty much re-built mechanically as a project and to also help with the $4.00 plus a gallon gas prices we had for a while

The last bit of problem I had to clear up was a code saying it was running lean. And one of the possible causes (but was not mine) for the neon to throw that code was a known problem of a cracked exhaust manifold and I do know that our H2's got a nasty habit of having the heads of the exhaust manifold bolts to break off. Maybe you have "many" of them broke and now have an exhaust leak causing the computer to throw the lean condition code.

This is just a thought and may not even be your cause but may be worth a look.

This is also the list suggested to look at in fixing the problem on the Neon

low fuel pressure
injectors
coolant temperature sensor
MAP sensor
O2 sensors
exhaust manifold
engine parts tolerance

The neon project pics are posted through out here http://s220.photobucket.com/albums/d...heri/?start=40 if you got some time to kill

Yep. Thanks. This was just the actual answer that I am looking for. I asked my dad about it yesterday though but your explanation is better, I guess

My truck has been running fine no idle issues at all no CEL. Yesterday I was sitting at a light then all of a sudden I noticed the pitch of my exhaust change the truck started idling rough then completely shut down. I restarted it and no CEL light came on or anything. I cleaned out my MAF and checked the intake tube no issues. At a complete loss now cause the dealer probably wont be able to figure out what the heck happened with no CEL.

Still no troubles here after my dealer visit a week ago....

no problems here since gasket was changed...
