420A Confused on Idle issue

[david-b]

I dont know man, I beleive Dave has already tried all of those.

I guess his car is just cursed

Tell me about it. I go outside to scrape the snow/ice off and the battery is down to 4 volts. Bah.

Thats very weird, have you check for an electrical drain? Try disconnecting the battery and see if it still dies. Just throwing out ideas

You say that the EGR is new; I would test it again. Try a block-off (even if it is temporary) and see if that might help.

Only when I gets cold. Car can sit in the summer time for months and not lose a drop of power. It gets cold, and it drains when sitting, even for a day or two.

I have a block off plate, never installed though. Have emissions. The old EGR was throwing CELS constantly and had mad issues with running and idle. New one here has been great. Cleaned well and works well.

I would have to scan the ECU to get an idea whats going on.

You know that droppoing into neutral actuall uses MORE gas correct? When you let off the gas and decel, the ECU cuts 100% fuel meaning it stops feeding any fuel to the motor. When you step on the gas it resumes operation. The ECU uses the trans to geep the motor spinning.

I would suspect you have a vac leak somewhere or the ECU is reponding to a lack of vacuum from the stage 2 cams. Timing could be a possability if one cam slipped a tooth. Like I said there are a lot of things that can cause this. Our cold ass weather is another if you have just installed the cams this summer, this may be a characteristic of cold weather driving.

The Crower 2 cams I had wouldnt idle very well at all. We went through a lot of altering setting in the emanage and throttleplate to get them to idle.

Actually you dont have emissions Dave. Your a 95 and if you pass one time this year, you will NEVER have to test again. That was a new law late last year for ILLinois residents.

No timing slip at all. The drive to idle problem isn't just the cold, it's been all weather.

The cams actually idle really well IMO. I was expecting worse.

I heard something about that with emissions, but can't find anything about it. I had it tested last summer. How does this work?
