Okay, it's running again, but..., 1.8 L-Jet Options

[jd66921]

Okay, I got my car running again, but not perfectly. But, I am confused!

Everyone told me to check for vacuum leaks, which I did. I got one of the pipes
to the S boot snapped in. The other one is pretty tight anyway. Not pefectly
sealed yet. This morning, I was checking the car over. I pulled spark plug #4
and found it wet with gas?? I would have thought that the car would have been
lean with air leaks. If I had air leaks, there would be too much air. Also, the air
flow sensor would not open so the mixture would not richen? Am I missing
something? I did cap off all the lines from the air box. Anyway, I pulled the
electrical connector off the cold start valve, and tried it. It started after about
5 seconds. It ran for a minute, and then died. It would restart, but die pretty
quickly. I stopped to think about all of this. Three heat exchangers were hot, #2
was not. That plug always looked good/lean?

Maybe #2 has an injector problem? I want to fix that cylinder first. How do you
remove the injectors? I've looked but haven't found anything. Must be easy??
Do I NEED a new gasket?

Then I can work on the engine dying problem. Maybe it will idle on four
cylinders? Nah, can't be that easy!

Obviously, I will start to reconect everything to see if anything is causing a
problem, but I am excited again!

How far out should the idle screw be on the throttle body? One turn, more?

Thanks for your thoughts,

Jeff

there are others here more knowledgable than i, but i'll give my two cents worth. for the screw on the throttle body, i usually screw it in or out, whatever it takes to get to about 900 rpm idle. but... that won't be accurate unless your vacuum system is tight.

for the injectors are concerned, they're not hard to remove. unhook the gas lines, pull the electrical connector, and then loosen the bolt at the injector. it should pull right out. might as well replace your injector seals, they're cheap insurance.

my 1.8 was running terrible recently. i determined it was an elecrical issue and on a hunch replaced the plugs with bosch platinums. no mo' problemo, runs great now.

ymmv of course, hope this helps some.
