yeah, if just a surface cleaning of the injectors did that I would either get them professionally cleaned and tested, or for not much more $$ get the ford injectors.

I played with the idle control and the AFM a little and was able to get this out of it. It's a start. Getting new tires this week so I can drive it more than a quarter mile.

By ford style injectors, you mean these?

Those injectors look right. Just make sure to get 17 or 19 pounds to keep the stock amount.

The video link doesn't work. Says it's private.

I set that thing to public to start with. . . Try it now. It idles high and it skips a little but it's better than I expected.

What kind of can of worms am I opening by getting the 19lb? The car is chipped so I might actually be able to make use of them but would I need to get a 3 bar fpr (especially since the pressure is low with the 2.5 bar fpr in the system now)?

I have no clue when it comes to etas. Generally the ECU is supposed to be able to accommodate for it but that's hear say for me.

The idle sounds like you have a vac leak in all honesty. It's just high enough that the car still drives fine but you're probably killing fuel economy. You're def close to getting it to run well.

19# will run fine, the ECU will just shorten IPW. If your have a good chip it should be able to make some use of the larger injectors.

Got the 19lb injectors but now it runs a little worse. It's still idling high (betting you're right about the vacuum leak) but it's now it's running very rich and missing intermittently but heavily once it's warmed up. If it were another car I'd put a timing light on it. I tried plugging the o2 sensor back in to see if that would give the ECU enough information to balance the mixture back out but it doesn't seem to work. I ran it for a couple years with the o2 sensor unplugged (except to get it smogged) so I don't know if the sensor is good or not. I'm getting a pretty solid .5V which should tell the ECU to lean out the mixture correct? Or do I have that backwards?

Thinking about swapping the stock injectors back in until I can figure out what's going on with the vacuum leak and o2 sensor but I don't want to jack around with the seals too much.

vacuum leak will hose the o2 readings anyway, I'd suggest putting the stock injectors back in and fixing the leak first. Do you have a stock chip you can put back in as well?

+1 with tony. The old injectors probably spat so it was running leaner than it should have. Now that you have bigger and better injectors, it's almost flooding.

So I know what tomorrow night will be. . .

I do have a stock chip in a separate ECU. There's a new BMW specialist shop less than 2 miles down the road. I may have them smoke test it to find the leak as well as give it a once over for safety. After getting the new tires, it actually feels pretty solid on the road but who knows what's lurking.

Smoke test is probably a good idea. I would still do a compression check.

So I had a setback. Changed out the injectors again and the stock injectors ran way better. I still had a miss that developed after it was fully warm. Apparently, I had a fuel leak though. Got tags for it Thursday night and cranked it to go put gas in it and had a flash fire. I'm gonna have to go through the hoses and rubber in the engine compartment again, check into the wiring harness in several places, the air box is damaged and a few other things. It's not a total loss but it's gonna be a while before I'm back on the road.

Thanks for the help - y'all made more of a difference for me than any other resource. I'll be back when it's time to try cranking it again.

That's terrible. Had a near miss on that myself not long ago. Got tired of fighting a rounded bolt head under the hood and decided to weld a cheap wrench to it to crack it loose. Didn't think about the metric shit ton of carb cleaner I just used to clean the area off. I was lucky I didn't lose my eyebrows, but had to extinguish the under hood fire as I saw flames rolling down the bell housing on top of the trans...Hope your damage isn't too extensive, I got lucky any the only thing hurt was my pride.

I had about 5 minutes straight of Three Stooges behavior. Opened the hood and the flames jumped up near the ceiling of the garage, so I closed the hood. Decided I needed to get the car out of the garage and went to start the car again - then realized I was about to dump more fuel on the fire. Rolled the car out by hand and tripped over yard tools. Finally got it out and didn't know what to do so I got out the hose and the decided that was a bad idea because it was a gasoline fire. In the mean time, the fire burned through the hood release cable so I couldn't get the hood open to do anything with it. When I realized I didn't have a handy fire extinguisher, I ended up spraying water from the garden hose up though the gaps around the front of the car where the worst seemed to be. Add in a lot of running back and forth and in circles - Larry, Moe and Curly couldn't have done it better.

At some point looking back it'll be a great story.

I'm going to try to do some cleaning and cataloging of what's damaged tonight. After looking at it a few times, it could really have been worse. The lights, windows and all of the electrical seems to work still. The damage is limited to the top layer for the most part and there's a lot that is pretty resistant to the amount of heat the small fire created. The cap to the air box melted a little, the coolant reservoir and the windshield cleaner reservoir will need to be replaced but the cover to the relays is still fine. One of the plug wires melted and the two upper coolant hoses melted some but the distributor cap seems alright.

All of that is easily replaceable if I have the cash - I'll just have to spend what I've saved for suspension revitalization. My biggest concern at the moment is the wiring harness for the injectors and sensors.

Question - are the Bosch wires on Pelican the good ones or do I need to spend an extra $100+ to get the BMW wires to get back to stock? Is there a better upgrade to the stock wires for a reasonable price?
