I wouldn't bother with the screen. The only failures we see are sticky solonoids, that in most cases can be cleaned with them on the car (in other words, on the OUTSIDE of the valve).

Come on out here. I have MSD'* and still have my stocker OEM coils too. I also have a Megger to test them, and can temp cycle them for you. If your MSD'* look good, I'll laser engrave the cylinder numbers on them like I did mine

Hey Will .. The laser engraving sounds cool!

I'm with Will...if he says clean this or that I either do it or keep quiet until I get to it. lol (Still haven't pulled the wheels and power washed yet) I did pick up some dielectric grease though.

Hmmmmmm ... calculating the cost of a cross country drive, time off from the JOB, speeding ticket or two vs. cost of shipping my MSD'* and a case of beer!

Laser engraving is an awesome idea, was looking for stickers but haven't found anything suitable.

The next time I am in your neck of the woods, the first round is on me (warning, it'* a rare event for me to be in the pacific NW).

Was thinking of temp cycling mine with a friggin torch, but then thought it might be better to use the car to warm them up.

3 times??? You just had to make me drool!!!

That looks awesome.

Bill!! No post whoring!!

Hey I'm mildly interested in this screen. My current setup seems to over power my EGR valve and leak out the sides. I've tried two different valves and didn't get it fixed. Maybe the pressure drop across a screen will help that out. Or I should just get my exhaust done.

I deleted TWO WHOLE posts of Bill'*!! AAHHAHAHAHAHA

Sorry. Had a net glitch at work.

I'll be wrenching things this weekend.

I'll get the specs the guy at TOMCO asked for and have him send me one. I'll try it for the hell of it. Probably take a week or two to get it. Maybe I'll ask nicely for two so he can have two test subjects (assuming your pipe ID is the same as mine). Worst case, it does nothing and I pull it out.

But then again, Will said not to bother .................. :?

Check it out. Seems like it might become a maintenance item, screen/basket eventually becoming plugged with carbon. Wouldn;t that plug the passgae and throw codes? I am guessing it might even become just like an EGR block off, which is a big NO NO. Am I talking myself out of this? LOL this might end up in the "bad myth" thread.

Sorry for all the posts. I am on the road, in a hotel, no one to drink with, and bored as hell.

Plugging up would be a concern of mine, too, and I've never had, nor heard of a plugged orifice on a DIGITAL EGR (1990-1993). On the linear, I can see the benefit, but again, the plugging is an answer I'd like to hear.

OK, got some work done tonight. Here are the results:

Switched MSD coils out for stock one at a time ........ no change

Swapped MSD wires out for stock ....... no change

Everything checked out with the multimeter, coils and wires. Stock is on now, as well as the stock AC Delco plugs.

Tested EGR solenoids per DRJAY'* hyperlink, resistance was a little higher than spec'd, but seemed OK.

Did the 9v test, lo and behold, the solenoid for the large orifice is not opening all the way. (I know you guys said to do this first, but the car was hot at the time and the coils are easy, besides, I had fun with a rum and coke in my hand).

Ripped off the EGR, pulled it apart and cleaned it. Swapped the pintle for the large orifice for the small one (I don' t think our car uses the small one). Cleaned everything up with Throttle Body cleaner, lubed with zoom turbine oil. Put it back together and 9v tested again, works l;ike a champ. Going back to Advance tomorrow for a warranty exchange (3 month old EGR). I think I am going to clean and lube it before it goes on the car.

Threw it back on the car (old gaskets) and idle very smooth (I thought it was smooth before). Test driving!!!!! made a few runs, running much better. All was great, until the last run. On a hard acceleration, shifting from 1st to 2nd, we get MISS MISS MISS then shift. Range is smooth up until then. Still feels like a misfire.

I did take my old stock injectors to my rebuild guy today, but he could not find any specs (using the number son the injectors, I didn;t have the GM part number with me). He flow checked them, but again, couldn;t tell me the flow rate. He stuck new filters in. Spray patterns looked great. Feeling that my hard starting issue may be due to the injectors (and wondering if they may not be just quite right maybe even causing the miss), I am sticking the stockers back on tomorrow morning. Before they were replaced, I could make smoke roll off the tires. Now, I am lucky to break them free (they were replaced strictly as a preventative measure, I know - if it ain;t broke, don;t fix it).

If they old injectors make everything kosher, then the JET chip and 2.2 pulley go on tomorrow as well. I am hoping they do as I want to put the MSD coils, wires, and TR6'* back in.

Any advice?
