Shaking, smoke, and after a few times perfect?
Hey,
I couldn't find anything that sounded like this in the archives..
I've got an 87' Base auto, and it's ran [almost] perfectly since I got it [july 1~05].
But then on Sunday when I tried to start it up to leave Church it shook bad and let out a little smoke so I turned it off let it sit a sec and fired it back up and it ran just like normal.. clean exhaust burning and everything. and it ran perfectly the rest of the day, even from a 3 hr sit. [I was only at the church probably 45min to an hour..]
Then monday morning I couldn't get it to fire up normally and it smoked so I had to drive my project car to work [which is still leaking coolant and kinda smacks around unless you're very slow to let out the clutch - another thing to deal with :P], it smoked more, and I couldn't tell what color it was... either very light blue or white..
I pulled the spark plugs and listened to the pulses and that all sounded normal, [though the rear plug was pretty wet], checked the oil and transmission fluid and those were normal. after messing with it those few times I did get it to start up and idle normally.. everything seemed normal, so I let it sit over night and then it was rough again this morning.
:/ I'm not sure what to check now.. I'm really hoping it's not major, because the project car still isn't ready to be a DD.. [suspension is also super fluffy on it..]
I'd really appreciate any help.
Thanks guys!

I felt the wetness and I'm pretty sure it was gas.. though it was kinda dark. [it smelled and felt like gas.]
I looked at the smoke as well as I could tell.. it wasn't perfectly white, but it wasn't dark either..
[spark plugs are new as of when I bought the car [early july 05], and I've been running exclusively Chevron and Shell gas and it hasn't flooded once since I switched to chev/shell. - until now]
The CAS has the original nut cover on it, so I'm pretty certain that the timing hasn't been changed, and its always idled a smooth 900/950 [factory says 950 for the Auto].
I forgot to mention that I've had a cone filter with a modified air flow sensor on it for a month or so.. I switched back to the orig. airfilter/ sensor, right before it ran normally last night - but like I said it was back to rough this morning :/
What would gray smoke mean? Too much fuel?
If the injectors are the problem, I have been meaning to take all 4 in to be sonic cleaned after I get the project car up to DD status.. [Because I ran the car on Arco july 05 through april 07]

Not necessarily, like I said it did it on Sunday after only sitting an ~hour.
and then later that evening it sat for 3~+? hrs and it was fine..
>_<
What could it be aside from a coolant or oil seal in the engine? [I want to be sure of what's going on if I have to rebuild it ~_~... since I just did that to the *Project* car :P]
I don't know how to check if it's dumping too much fuel..
Thanks
