I just cant figure it out. Cant find an air leak, I have good compression, good plug, good wire, new K&N filter...whats the deal. It happened very suddenly, from perfect to crap in one second. And it dies at idle, even if im going 65, if I let off the gas and put in neutral it dies.

 

what else would cause this??

 

Take a real close look at the air intake, the bellows can crack deep inside and be hard to see at first. Maybe even remove the section of plastic intake and look underneath, all around. Flex the tube to open gaps.

 

Thanks, Ill just keep checking for a leak. Are there any leaks that would be harder to see? Also, Where is the long hose at the bottom of the charcoal canister supposed to go.

 

check the o2 sensor make sure the connector is tight

 

I took mine to the dealership and they said i had the wrong plugs(they were autozones), the air intake hose cracked in the bellows, my fuel pressure regulator was bad, my lower metal intake plenum was cracked, and my injectors installed incorrectly. Spend a bit to go through the list but bound to find the reason.

 

Any idea what that means? Seems to me that anything but a correct installation of the fuel injectors would mean a no-run situation.

 

I'll check the o2 sensor tomorrow. This problem is just throwing me in circles. Im actually starting to think that it is just a clogged injector, but then I dont think that would cause it to die at idle. Somebody out there has to know. What else can I check?

 

long hose is supposed to be routed into the frame. But it basically does nothing not attached to anything

 

Get a can of starting fluid spray and spray around all your air tubes, if there is a leak, you will see a difference when the spray hits the leak. I found one this way in my rig. Never would of found it without doing this.

 

Have you replaced the distributor cap?, it could have a crack in it some where.

 

Brilliant, I didnt think of spraying starter fluid on the hoses. It will just rev higher if the leak sucks it in right? Can I use a can of Ether?

Distributer is new.

 

i would stick with carb cleaner and yes it will rev up a little if there a leak

 

Does it matter that I don't have carb? Aside from a vacuum leak, what would cause the engine to die at idle AND stumble and hesitate during acceleration?

 

Just an idea.....there is a "idle solenoid" on the carburetor, if it's not working, the engine will not idle.....it's located on the upper part of the carb, toward the firewall and has 2 wires, check it, it could be the problem.

 

No Im fuel injected

 

I had two clogged injectors, and the engine would run, idle, accelerate, but I would act like it was missing. I've had the O2 sensor go out, but it turns on the check engine light. So it's probably *not* the injectors or O2 sensor. Test the vacuum and fuel pressure, check the computer for any codes. Maybe it's as simple as the throttlebody clogged with gunk?

 

Thottle body idle speed regulator airway restricted/obstructed, use the SEAFOAM, do a search on this site, very usefull stuff. If that don't work, probably EGR stuck open. Would let hot exhaust air in mix at idle, not good, cause your problem.

 

Don't know if this helps, but I'm getting a clicking sound coming from the ECU right before the engine dies. And sometimes it will click without the engine dying. Any thoughts on that?

 

Help! this is killing me.
