I answered in your thread on the E30 forum, but I'll say it here, too:

Injectors. Pull them and clean them. That random misfire points toward injector problems.

i r b here....wit teh snorkelz.

and flippurz...gotta haz teh flippurz.




i am up way too late again searching teh interwebs for interwebz stuffs...

anyway, i would agree with ken on checking the injectors, but i thought that you had swapped them out and cleaned them earlier?? (see, i can 'member stuff, too...)


but if you haven't run any seafoam though i would do that,

and road blast.

probaly gotta stretch her legs a little...

besides, why u post in teh e30 section...i thought that we already established they don;t know how to do anything but swap m50 into that chassis...

odd thought, but how old is the gas in the tank? I think you said you've been driving it all week, so its probably fresh.

when I got my 318- PO was running 87 octane, and it was probably 2month old fuel. Engine ran like a donkey...

Because of the 87 octane, the engine was retarding the time to compensate. So maybe the timing is off/old gas/I-have-no-idea-but-this-sounded-good-before-typing-it

Replied. I did pull them and soaked them overnight then Seafoamed it. Might put some in the tank and oil then do the vac line again.

Haha, I've been beating on it now that it doesn't miss much.

I ran it empty and filled her up with some 89!


I'll keep driving and report back. I need to fix my fuel pump because the fuel sloshes out the tank when I turn hard lol.

Try some 93? the 318 M44 ran SOOOO much better on the 93 than 89. Though it costs a bunch more.

She's running pretty good, almost perfect. New O2 senser helped I think. Slight miss at idle, I believe it's number two because using a temp gun it showed around 75 degrees or more cooler.

Still has the little hesitation under load, but it's much much reduced. I'm thinking it's low compression I'm number two or a bad fuel injector.

Sorry for being dark, here is the top of the floor. I cleaned it then sprayed bed liner on top. You can see my sign I used to "rebuild"the floor lol.

Pressed in a new passenger ball joint today, I think I'm going to get one for the other side too, has a wee bit of play in the wheel. The passenger side had a ton of play.




I think I'm going to purchase these as well, thoughts?

Can't figure out the high and wompy idle either. I cannot find any vac leaks using the spray carb cleaner technique. Not sure what else it could be other than injectors.

We just got the 633 injector set back from WitchHunter and they are a world of difference. The car actually idles at 750 now and doesn't stumble off idle. Get those injectors and I'll bet it cures your idle problems. BTW, that's darn cheap!

Ordered!

Almost ready to put the interior together:

Applied bed liner to the driver's side after a clean and vacuum







Cleaned the used carpet I bought






Then used black spray paint (don't hate)




I put on a LOT of coats. Between them I would brush the carpet to make it a little softer and make sure everything was covered. I'm going to do another coat or two tomorrow when it's nice and completely dry. We'll see how it turns out.




Cleaned the door cards





Then used Duplicolor fabric dye in flat black





Should have it all done this weekend.

Looks good, but holy smokes, isn't it going to get you stoned from the spray paint fumes from now until eternity? Hard to imagine that carpet ever not smelling like spray paint now.

Guess I'll find out lol

Got a couple of things done today. First, started putting the interior back together, have the windows all wired up now (weren't before) and mostly everything done. I'm also trying to fix the leak around the fuel pump assembly, if I fill it up the whole way it spews out. I put a new o ring in and I'll fill it up tomorrow and see what happens.





Front of the interior is mostly done, needs a cleaning now for sure. I'd also like to redo the seats sometime, ideas? Products? Experience?

Again, low quality low light pictures.






Check out my new gas pedal yo, been driving it without one at all for the last month! lol




Injectors showed up, look very very nice. All new O rings and the like, not bad for 68 bucks shipped total.








Runs GREAT!! No miss at all, climbs all the way to redline. I figured something was up with the injectors, the rest of the fuel system is new (soft lines, filter, pump, pressure regulator) as is the spark plugs, wire, cap, and rotor. I also used up 3/4 ish of a tank and only got 94 miles. One or more of them were stuck open for sure. One other thing to note is the the injectors tested perfectly with a multimeter.


Now the only problem is idle, there is no miss anymore but it isn't quite right. Bumps up and down sometimes, and is always high (1500rpm if not more)


I cleaned the ICV but maybe I killed it in the process? Like I said I don't think there are any Vac leaks but who knows.

Can't ICVs just wear out? Maybe yours is just past the point of no return. Glad to hear that the injectors made a difference though. Things are looking good.

No idea, but I don't think they're cheap.

You're right.

So fast!





Interior is mostly finished, definitely acceptable to drive now!

How's she runnin'?

I bet that thing's a rocket!

Glad your work payed off

Sure is Cj!

It's running perfect except at idle it sounds like it has an aftermarket cam in it lol.
