Extremely rough idle, and stalling...
 

My 95 e350 small block V8 (not the ranger) is having major issues right now. It runs exceptionally rough, and stalls. give it gas and its 'ok' but still stumbles a bit.

Spark is good, and fuel is fine. We found out that tapping on the EGR control thingy, that the truck, idled great, so we bought a new one of those. Installed it, and then the truck wouldnt start at all...

Finally after actually putting it completely back together (it was just sorta sitting there) it started...after discovering that a wire, (i forget what its called, it comes off the distro, its the 9th wire, goes to something else.) anyways that fell apart so we replaced that... anyways the problem still exists. A good friend of mine, spoke to a friend of his, who thought it maybe the EGR itself, so we took that off, and visually inspected it, however have no way to test it... any ideas? A new one is $90. I cant afford to keep throwing new parts at this thing... yet I need the truck for work.

Any ideas?

Sounds like a vaccum leak. Now finding it is a real problem though...

no telling is the check engine light on

Could also be the IAC vavle.

make a video that will help us alittle

Ugh this truck... im ready to take it to a shop...

im starting to think i should replace all the vaccume lines as well, that thought actually crossed my cranium.

So far I put $90 into this thing and its ntill not fixed, while it no longer stalls in park, it now wants to stall in gear. >:(

I put an ew IAC valve in it, and an EGR regulator in it... the egr valve checks out as 'ok'

I also think I may need a new mechanic friend hes dead set on it being a fuel problem... his idea: drop the gas tank which has 35 gallons of fuel, and replace the fuel pump...

My othe mechanic friend has so far sided with everyone else as it being a vacuume leak...

the egr valve could have carbon built up. you can take it off and spray brake cleaner or something thru it and it could help get the carbon off.

Maybe if you had a time machine to 2010 this advice would be helpful for him lol.

Very True. ha
