    Hey, if you go the route of deleting egr, I would really like to have one of the 91-92 Cali tubes... I had mine spot welded to the catback :/ Pm me if you wanna sell that, and it still has threads at the bottom by some miracle.

    The EGR air tube is easy to get - the connector at the bottom has eluded me so far. As below....
    I believe the 91LX Escorts all had the EGR pipe coming up from the outlet end of the catalytic converter, via a nearly vertical tube leading into the EGR valve. The 'federal' Escorts in 92 and 93 didnt have EGR. With the 94LX Escorts, all of which had EGR, the pipe now was connected from the fitting in the middle of the exhaust manifold, around the side of the head, to the EGR valve.

    I have one 91LX that was made for the California emissions market, and one that wasnt. They seem identical under the hood. Both of my 91's had that same early kind of connection between the output end of the cat converter and the EGR valve.

    I have bought catalytic converters that had the tubing bung on the output end, but were listed as 'cant be shipped to California', possibly because they didnt have the best mix of the scarce elements inside; platinum, palladium, and rhodium. (I dont live in CA, so not a problem for me..) I think the cats for CA have a mix that is more expensive (more rhodium) than those for the federal markets. The actual mix of the three scarce elements may depend on the market price for each of the metals; which has varied a lot over the last dozen years.

    With my 91LX Escorts, getting the pipe that runs between the EGR valve and the fitting on the output of the converter pipe took some searching. It was a PCI-170, made by Pollution Control Industries. I now see them listed for the 91LX Escorts, under "exhaust and emissions", as a "catalytic converter air tube". And fairly cheap too.
    The connector between the bottom end of this air tube and the 'bung' on the cat converter outlet pipe is usually badly rusted. So far I have not found any source for this connector. The ones in junkyards are not easy to reach (being underneath), and usually would require a good operator with an oxy-acetylene torch to get it off of the car. Most junkyards wont let me take my torch set into the yard, and wont remove the part for what I consider a reasonable price. In fact wouldnt even go to look.

    With both of my 91LX's, I couldnt get the EGR air tube unscrewed from the fitting on the cat converter; and didnt want to set the car on fire by trying from underneath. But it wasnt hard to unscrew the EGR valve at the intake manifold, to undo the cat converter (and the O2 sensor and the oil pan brace), and lower the entire thing down and out of the car. Then I could clamp the parts in my vise and soften-up the rusted parts with my oxy-acetylene torch, to finally get them apart.

    Yeah, it makes pulling the intake a
    Mine had cracked due to my brother in law jumping a snow pile. Its been OK, my only problem is that I need to remove the egr valve from the manifold because if I use rtv on the intake gasket, I can't get an angle without disturbing the bead. The other problem is dropping the exhaust might prove to be a pain if it comes up.

    I undid the exhaust joint where the cat converter connects to the intermediate pipe (the one with the flex section). I had the nose of the car raised up, as I always do when doing engine work. I always use LOTs of antiseize compound on exhaust bolts/nuts.

    Since I live in a dry climate I dont have any issues with rusty exhaust bolts (or rust of any kind that I can find) just a good In-pact gun and they usually come right off.

    its still a pain to do anything with the intake manifold with that EGR and tube on the back.
    blow an intake gasket well time to loosen the Cat first. EGR delete might be next after Cat delete if it is worth the trouble

    I would bet on specifically a 91, a cat delete would cause issues with the egr.

    I'm not certain, but I think 91 egr will be hotter than 93+ egr due to be directly after the cat. I would also assume it would have less fuel left in it as well.

    the header set I linked earlier, that gets rid of the Cat, has the EGR port on the manifold.
    my plan was to get an EGR tube from a later Escort/Tracer and connect it up that way.

    thats if i dont delete it all at once but thats more work :whistling:

    If you unplug any egr related sensor, delete complete lol

    thats if it doesn't mess with fuel trims, I think you need a computer from a non-EGR car so it doent lean out and the Check engine light not to be on all the time.

    If you unplug an egr sensor, it will adjust fuel and timing for you as long as the egr valve isn't stuck open. I prefer how they drive with egr (I notice more low end torque) but some say they drive better without egr. You may lose an mpg or two.

    "Insufficient" egr codes are not the same as no egr. A dirty dpfe or leaking egr can cause lean/rich issues as well as reduced low end torque and spark knock. If the valve is closed, you can unplug the dpfe and it will run great.... Better than with a dirty dpfe. Yes, you'll have a code, but it will run fine.

    I hit a bad pothole on the highway 2-3 weeks ago (on right side of car). Finally got around to inspecting it, and it's a bad outer tie rod end on the right side. Left side is fine. Symptoms were that feeling that I broke something after hitting said pothole, and pulling to one side on acceleration, and pulling to the other side when braking. There was no vibration issues! So weird. Outer tie rod ends was a Moog Problem Solver that I had installed on April 27, 2003, around 158K miles ago

    Last week, installed a new radiator, t-stat gasket, and serpentine belt on my friend's Mom's '95 wagon. When searching for good deals on parts to replenish my spares inventory, I came across this listing on Amazon:

    https://www.amazon.com/dp/B000C36BGM/ref=sr_ph_1?ie=UTF8&qid=1495475445&sr=sr-1&keywords=4060530

    It turns out that Continental has bought out the Goodyear name, so Gatorbacks have dropped off the face of the Earth. As I have been pleased with the service and quietness of those belts, I was happy to find out that Auto Parts and Paint still has some in stock (Amazon just changed their listings to say "Continental"). Only $5.99 each with free shipping, and no sales tax in my state (CA).

    As I write this, there are seven left.

    Even though I saved the receipt, auto parts store wasn't interested in honoring their "Limited Lifetime Warranty" on the tie rod end. Emphasis on "Limited". So I ordered one off eBay. I will be driving my other car until I can fix this.

    Stole a CV shaft from my 91 for the 96, also pulled the 96's speedo and fixed a leaky dipstick tube (pictured). I am probably going to steal the new crank dampener and the 85mph speedo from the 91 tomorrow.
    The 91 has one less digit, can it's odometer be swapped over? They look to be the same width. Either way, if I swap them straight up, there's only a 5k mile discrepancy.

    I'm swapping Speedo's because the 96's bounces and the cable looks fine. The crank dampener on the 96 has a wobble which makes the serpentine belt or the timing belt squeak. The 91 will be having ALOT of work done in about a month . don't worry about all of the parts it's donating.
