Marcelo may be a helpful guy, but Id still want it timed. Id go elsewhere to ensure that it is done. He may be good and low cost for doing other stuff (TBD), but Id hate for you to have the timing way far off.

Did he/you replace the EGR gasket?

http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1493472

Code 44 remaining would be sensible given that the O2 is likely not working. Given how cheap it is, Id just put it in, before you get it timed right, and see what it does for you.

Yeah... I still need to go somewhere to have it TIMED. wink

As to the EGR, it wasn't replaced.. just cleaned with less PB Blaster than i would have used (I see the IACV in your post. Same tactic used to clean not replace one was used on EGR. I would have doused the pintle, not just gently squirted it) but I feel some improvement, no "run on" etc etc etc, more power.. just still code 44. No "exhaust whistling" and I still have tune-up parts as suspect... for the idle, etc...

And whatever was on the EGR was put back on, he had some real nifty 3/8" ratchet with extension (not too big) and some U-joints (?) and got it off only with removing some kind of 2-screw bracket. Pretty slick.

Funny, I also have the "slight shake at idle." I believe it can be dialed out... Feels like ONE cylinder is weak, in most unscientific terms possible. yes?

Timed it by ear................. Means it isn't timed.

Not your fault.

So, yeah... Marcelo seems honest enough, and he cleaned the EGR pretty efficiently just unsure how well, but his opinion on engine timing is troubling.

The car he is working on now? Looks like he is taking the transmission out of a big Snap-On (ok maybe not Snap-On but) come kind of big box truck, based off some kind of full-size van or truck...

Youre right, I showed IACV, not EGR - have EGR cleaning and gasket pics elsewhere (gasket is ruined when EGR is pulled, recommend the gasket with the screen in it)...

need to dig those pics up!

JHZR2, Do you know anywhere I can go to to get this thing timed without any reasons why the timing is "pretty much ok"?

Why not? Cant you get a ride to and from work for a few days? Can you get a ride to and from the shop?

There are a ton of shops on the street that the DD is on.

I had done my IACV on a previous engine, that is how I knew right away smile

I drove through Linden and Rahway today, all by the big Home Depot and BJs out there.

Starting to be A Jersey Affair! LOL

I *may* be able to pull that off. It's just a matter of finding one willing to do it, and ho wmuch they want! Then to find the ride out there..

***I get a lot of financial support from Mom, and she doesn't want me spending money on this. Therefore, she is reluctant to help me, and if she knew I was spending money on it, might not drive me in an attempt to impede my progress.

This is why I say, I have a day off tomorrow to take money and do whatever I please.....

Marcelo even wants to look at it, but his position on timing seems clear.

When I had the second car, I used to just do whatever, whenever. So maybe I am going to enjoy Volvo #3 but have all this "Mom driving" drama until that happens..................

I agree, and with tomorrow's daylight, I will make a real diligent effort to get the 02 unscrewed.

I may bot be able to put the copper on the thread,s but so what! Right?

And then, all I have to do is reach way up to disconnect where the sensor plugs in, and maybe I can see if SES returns! Leaving only the timing issue.

I described the "strings attached" since my Volvo went away frown (I forget what was up with Blazer at that time but the Volvo was way better.)

Just man up and remove the O2 sensor already.
Install the new O2 sensor.
Connect the wiring.
End the thread.

Wrong, not if you want to be able to remove it later on.

I don't see the issue, cut open the copper anti seize packet, apply a small amount around the threaded part of the sensor (emphasize small amount and only on the threads)and screw it in like a sparkplug

Here's a tip on the connector, look carefully at the new part then look under the truck and figure out what needs to be depressed, don't just manhandle it, they can get old and brittle. Also sometimes the connector end is hard to reach and work with. Generally the the socket is connected to some part of the body with either a friction pin molded into the back connector that fits into a hole on a bracket or a cable tie. Sometimes easier to press that out and drop the connector , (this gives you more room to work) then disconnect the sensor. If your do this just be sure to tie it back up when you are done. IIRC the Desno's come with some nice high heat braiding on the wiring, you want to make sure the wire is routed away from any exhaust pipes
