car dies after diy icv/sparks/lower air intake boot

started a thread earlier this week

http://www.e46fanatics.com/forum/sho...645&highlight=

i changed lower intake boot which had the leak and cleaned the ICV. maf was cleaned few days ago. i also changed spark plugs.

now when i start the car it sometimes would die when i hit the throttle and during driving (40-50 mph or less) it would die when slowing down. im probably going to take everything out again tomorrow to see if i missed anything. now the ICV wasn't as bad as in solidjakes video but i did clean it a bit.

i will get the codes read tom. but is there anything else i should be looking at? car was not dying before the DIY but i did experience a little sluggishness and figured it was time for plugs. any help is appreciated. thanks

o yeah forgot to mention new air filter. i didnt inspect disa valve but it looked in pretty good shape.

Since the car was not dieing before, its most likely a result of something you did. Double check the plugs make sure they're in properly. It could even be the maf. Once you double check everything get the codes and start from there.

i rechecked everything and found that cps sensor was not plugged in all the way. after making sure it's connected right the stalling problem towards the end of vid dissapeared

car stalling

with the new lower air intake boot in place car feels more responsive than before. the boot after maf has little cracks too but they dont go through so ill get that replaced next time around.

it still throws all the other codes and i ordered the scanner online to save myself the trips to the store.

how would i know if disa/icv needs to be replaced?

i hope to get these codes cleared with e46 community help

The disa o-ring should be replaced too, common problem even it always looks good shape. Indeed, it has to be replaced. $12 on Ebay.

that lower intake boot is pita to change, i gave up and just changed the upper one. Didnt see any cracks on the lower one, well what i could see from the top. GL

thanks can't go wrong with a $12 part.

For the DISA you can disconnect the plug and if a rattling noise goes away you need to replace it. For the ICV you would probably wait for a hard code on that. If you used my vid thanks.

Are you getting any misfires?

What O-ring are you referring to? Is it number 10 or 11 in the diagram?

^ There is no individual part number for the o-ring from what I remember, you have to buy one that is the same that is on there.

I replaced mine using an o-ring from home depot and a bit of rtv sealant. No problems yet and the seal is much tighter when mounting the Disa compared to before
