Compatible ECU/PCM?
Hi all - I've been chasing my stupid hesitation/stumble/skip/miss for a while, and I want to chuck an ECU/PCM/the thing bolted in the firewall on the driver's side at it, just to see.
Planning on hitting some junkyards tomorrow. If I find a 96 E350 with a 5.8 and E40d, great, but....well, maybe...
If not, would, say, an F350/E40d ECU work? Any way to tell?
Thanks!
Iain

Well, I went to the junkyard and found a 93 E250, 5.8/E40D, rolled the dice, bought it.
The good news - the ECU works in my 96 E350, 5.8/E40d.
Bad news, it runs EXACTLY the same. At least I can pretty safely assume that the ECU is not the problem (unless I got REALLY unlucky and found an ecu that failed EXACTLY the same way mine did). Going to take it back out and return it to the j-yard, $40 store credit towards a new hood or something.

Just saw his thread.. and yeah any 5.8/E4OD EEC will do the trick. A hesitation stumble/skip suggest a lean problem and any exhaust leak upstream of the O2 sensor can have that effect, so check the air injection system and exhaust manifolds for cracks, rust, breaks, particularly the steel tube across the back of the motor between the cylinder heads or exhaust manifolds.

Interesting - that makes a lot of sense.
It does not have an audible exhaust leak, but the EGR certainly seems like a potential suspect. It gets worse with temperature - when cold, the van runs flawlessly.
What about blocking off the EGR valve? If those tubes have a crack, I guess that'd not change anything.
Hmmmm, will go look now, doghouse is off. Thanks!

And the plugs do look "lean." Just took two out (they've been replaced 2x already trying to find it), and they don't look scary-lean, but lean considering the issues at hand.
IE, if I'd taken this plug out of a normal-running motor, I'd not think there was any problem. They're not WHITE, but on the lean-side of OK.
