1 how long did it take for you , to accomplish the whole task,
took a break for dinner, worked out in the cold dark driveway (with a nice bright shop light), and it really only took me about 40 minutes to get everything off and out, and about 20 minutes to get it back together
2 are the electrical wires and connectors easy to get back to the right spot?
on my car they were. all the lengths and natural bends of the wires tell you where each goes, not really any second guessing that. only trick might be one of the coolant sensors, which has only 1 prong in a normal 2 prong connector. Just make sure that one prong goes onto the correct sensor. no biggie there.
3 what if i dont own a air pump?
i'm not sure how much it actually helped. It *may* have jarred loose some contaminants that were deep inside the injector, or coked onto whatever valve is in there, but I didn't see any funk flying out when I blew them out.
4 you say-"first attempt". how many tries does it take,
it took me 2 b/c I didn't take off the idle control valve and cold start injector the first go, and even though people said it was possible, I didn't believe there was enough room to maneuver the fuel rail+injectors out of there in one piece, but there IS.
5 are there any spare parts i should buy
Some people say get new o riings for the injectors and fuel pressure reg if you're taking that off too (which I did). I got a universal set from Advance or somewhere like that and they looked about a millimeter too small so I didn't trust them. So I just oiled up the old ones (which weren't dry rotted or split) and reused them. Not ideal, but better than something that might not fit correctly. Ideally I would have bought a new set from the dealer or a place that actually carries them specifically for our injectors.
6 what was your drive like before and after>? jobs done
Better throttle response, a bit harder pull I guess. Just giving some life back to the ole eta. There was a lot of caked on crap on the tip of the injector (look at the pic above, the tip is supposed to be orange), so I'm sure it helped the spray pattern. Probably will help economy also in the long run. Actually the first time I fired it up it ideled really high for a few seconds, so I think they were working better but the computer didn't realize it for a while hah.
7 that site is great, and it states its easy, im just afraid to ruin my car.
I was too, and I thought I had.
8 how would i know if i need NEW injectors? would i know?
I don't know. I would call around to see if there is a place in your area who cleans injectors ultrasonically. This is a popular and very efective way to blast the years of crud off the internals. They may also be able to tell you how to visually inspect them better, although there's not much to see from the outside.
9 does the intake manifold come off too?
Nope. Again, I swore up and down it wasn't possible to remove the rail without removing the mani, in which case I quit the first time around. But some wiggling and properly/thoroughly moving the wires out of the way is the key. You will be tilting the rail towards you, tips of the injectors towards the opposite side of the car. The rail will come out first, followed by the injectors last, if that makes sense.
Good luck, it's not so bad after you get into it. I have the same reserves about working on things like brakes and anything to do with fuel, b/c well, those are kind of major things to dink around with if something goes wrong.
