fuel injectors
I returned from another great time at Funfest '07 with some new parts
and ideas for my 89 coupe. Went to Gordon's seminar and he always
talks about checking fuel injectors. So on the way home stopped at
Sears in Terre Haute and bought an Ohm meter and when I got
home checked my fuel injectors. 5 read 16.9 which is great but three read
8 to 12. So now with this knowledge, how easy is it to replace the
fuel injectors? I'm not much of a mechanic but I did buy this car to be
my new hobby. Gordon also recommended Lucas injectors but I can't
find any listing for these, he did say the kit from Mid-America which uses
Accel's were fine.
I'm getting 20-25miles/gallon and car ran great on road trip around Illlinois
but I guess I'm running on borrowed time if 3 injectors are going bad.

Hi Fun...It's really not that hard, but It's not something you're going to do in a couple of hours. The plenum has to come off, maybe even the runners. You'll need new gaskets for the runners.
I need to replace my injectors too, but when I do I'm going to replace the EGR valve and temp sensor under the plenum, maybe even the fuel pressure regulator, while I have everything off

I don't know if I'd worry too much about a few extra ohms at the injectors. I think vacuum leaks are more a problem with TPI's than anything else - I'm sure GK probably mentioned this, didn't he?
Did you happen to record his stuff?

RE: fuel injectors
Mating surfaces must be IMMACULATE at re-assembly. Like where the injectors O-ring seats in the intake. A speck of grit will allow a vacuum leak, and that's a tune-killer. As are gasket surfaces...

No I didnt record Gordon's talk but I sat in on 2 this year and 1 last year,
I've thought about signing up for his week-end class. Has anyone been to
his class?
How do you check for vacuum leaks?

If you do have a leak, there's NO reason to do ANY mods at all till they're tight.
You got a lopin' idle? If not, you're probably OK.

RE: fuel injectors
One easier method is use a piece of 3/8 fuel line about 3' long. Put one side to your ear and the other to listen around engine for a hissing. The hose isolates the area just where you are listening. Another way is to use carb spray, but be very sparing with it. If you find a leak, the spray will change the idle, smooth it out.

propane, like in a gas grill or hand torch?, Does the propane get sucked
in and rev the engine?

Does your idle hold steady?
