1997 Suzuki Sidekick JS 1.6l 4X4 manual, 120k
Throwing EGR code...managed to get it to smog last year but the light came back on...I'm kind of figuring that the shop did something sneaky to pass it. Anyway, I've replaced the EGR valve itself, have not replaced the SVS (on order; should have by 3/13/12) or the modulator (which is incredibly hard to find), and haven't been able to ream out the exhaust passage behind the EGR yet (I did find that someone had attached a bit of aircraft cable to a drill and sank that in the exhaust port but I'm a little hesitant. Anyone tried this?). My girlfriend bought the car from my parents knowing that it had the EGR code and that the problem hadn't been fixed and now after much crying, I have of course inherited the task of fixing it.
symptoms
1. car starts hard; doesn't like to keep idle at start up
2. loses power when gas is depressed (same thing that happens if you push the diaphragm toward the bell end of the EGR while it's running; I'm sure this is a clue, but I'm not a brilliant mechanic...)
3. related to 2, car barely makes it up hills because, of course, you have to add throttle and it doesn't like that.
4. rough idle when warm. It feels regular, so I thought it might be a bad hole, but they test good.
ANY help would be greatly appreciated. I like the car and I want my girlfriend to be happy with it. If all we can do is take it to a mechanic, that's a possibility. If anyone can recommend a decent mechanic in the Reno/Carson/Tahoe area, I'll check them out and we might be able to take it as far as Sac for repairs. Many thanks.
Steve, Reno NV

None of those symptoms have anything to do with a PO400 so you must have other issues somewhere.

Well.....for a whole lot of reasons, I'd like a second opinion.
'97 Suzuki OBDII reads PO400 exhaust gas recirc. and all of the symptoms point to possibly the diaphragm not working on the EGR or possibly the modulator and a number of other reasons down the line. I'm not a total novice, I'm just not a mechanic. So while I appreciate your having read the post, I'm going to have to hold off on your being the final authority.
Anyone else have any ideas?

Whatever you say Mr Wizard. I'll leave you to your infinite wisdom and EGR code.
4. rough idle when warm. It feels regular, so I thought it might be a bad hole, but they test good.
This is the only symptom that could possibly be caused by an EGR but judging by all the other symptoms you, I seriously doubt it.
