Ecomodding an Escort, the story so far...

There is one from a '92 Caravan w/ 95k km (59k miles) for $250 at Nieson Auto Wreckers.

If you want to try rebuilding it yourself.

emissions test results...

ASM2525 test @ 1900 RPM
HC PPM 10
CO% 0.06
NO ppm 84

Curb Idle test @790rpm
HC PPM 10
CO% 0.08

Previous result before mods, (can't find paper, took from what I posted here before on another thread)
Idle
HC PPM 23
CO% 0.9% (or maybe .09) but allowance is up to 1.0
can't find ASM 2525 numbers right now.


It's odd that HC is 10ppm on both, wonder if that's as low as the equipment reads or something.

Thanks, I saw that one, good price for the miles, but due to how the highways run and traffic is, it's a longish drive from here in good weather, and we're not seeing too much of that right now.

I'm burned out on rebuilding stuff for the moment, I'm thinking it's got some major troubles that a basic rebuild kit won't fix though, might need major parts which might be machine to fit deallies. I will probably put the old tranny aside for a few months and tear it down and rebuild it strong at leisure.

As I expected, first tank was awful... had hours of idling while checking it out, fixing it up and getting e-test etc, then was stuck in Xmas shopping traffic a few times, 80% city driving on snow, 1 day worth of that was plowing it and belly dragging on it, 15-25mph crawls, stuck on highway an hour yesterday, -10C starts with blower needed to de-ice, driving everywhere with lights, wipers, blower full blast annnd on "winter" tire pressures. Car went "cold" on any stop longer than 5 mins due to temperature and wind. Suspicious of my PS pump too. Tailpipe is restricting the exhaust, wrong one is on, still waiting for the right one to come in. Then that first fill the pump clicked off but tank needle only just made the full mark, so pretty sure it was at least a gallon short, I seem to remember getting 60 miles before it settled on full which is more like 2 gallons...... end result of all that, just 24mpg... call me a dirty rotten scoundrel, but I'm not logging it

You dirty rotten scoundrel! I logged my 15mpg fill yesterday after getting a steady 18 to 19.5 most of the year.

^^^I went looking for an appropriate smiley but found that one instead and couldn't wait to use it.

[GasSavers_RoadWarrior]

Muhuhahahaaaa, I guess I'd be able to guilt myself into logging it if it was "only" winter issues, but with probable short fill and exceptional idling times for maintenance purposes, I feel it's questionable data.

[GasSavers_RoadWarrior]

Holy sucktastic gaslog batman! This one went in, I guess I have issues to sort out. It was 95% short trip cold start city driving though, all the christmas errands. I guess Marvin would have been down around 18mpg on the same routine.

Uh oh... I didn't log in some of my sub 40 trips when I was having car issues during the fall.

And I don't think I'll be logging the time when I'll be bleeding my coolant lines next week.

Arrrrr that's a bit more like it, some highway runs, 29.77, probably remembering how to drive him now too. Still on the sucky side though. I thought 0W30 was worth 2 mpg in him before, gotta get it in there. I'd be happy-ish with steady 32-33s on soggy winter tire pressures, winter gas, winter temps. Thinking a rad block and warm air might be in order.

'nother tank, 'nother 'orrible lot of city runs.

I think I've got too much spark advance, he chunters and pings faintly at low RPM particularly when it's colder. Then in the 2K to 3K range where timing gets pulled by the ECU for NOx reduction he's fine, and higher up doesn't seem bad either...

Wondering how to fudge it, IAS, CTS, move the crank sensor, or widen the plug gap. Gotta pull some data on the EEC-IV and see how it handles stuff.
