rebuilt m20 2.7i wont idle kinda revs , found out problem hahah

[Bmwb]

well i got a mechanic to look at mine , and by the looks of it you could have a electrical problem thats what i was told and it turned out to be true aslong as your engine isnt messing up whilew revving it , i say go back and re check each plug could be corrosion , clean them up , and check that one c191 connect to your injecotrs mine was filthy... cleaned it you can by a spray for this and add electrical greese for better contact , linkable fuse < but i doubt your car would be able to start if thats blown but could check it

to me that sounds like too much gas..gas mixture is wrong to start. remove a sparkplug and check if there is too much gas.

ohh what he said dont start the car see if the plugs are wet u could have leakey injectors , pull off the vaccum line to the regulator check if there is gas going through that into the intake manifold regulator could be gone ,

Wouldn't the ecu regulate how much gas is being put in the engine , and would a new fuel filter cause this , also car will only run with out the IAC or the maf connected , if I try and connect the iac and the Maf as the car is running , as soon as I connect the iac to the throttle body the car dies, if I put the elbow close to the throttle body it's almost as if the car is gonna rev ��I'm posting another video

remove a sparkplug and smell if your engine is flooded. Im almost sure its fuel related

[King Mufasa]

I remember my car would do the same thing. You start it and then suddenly secounds later it just shut off. I managed to get home by accelerating the peddal to keep live.

I found that the plastic clips or whatever on the throtle links were no good. I think you should check that to see if operating right not shutoff

I cant tell you the part number cuz I never fixed it I just swap another engine.. but check the throttle links

[e30m20TurbO7]

I still haven't figured this out , if its flooded what could it be . i checked the c191 connector looked dirty a little bit , but I can get it to run without the air box so im pretty sure the injectors are working . Iac buzzes , tps clicks , afm operates , I have no fuel obstructions , I have a new fuel filter in the rear and a little fuel filter that's see through up by the fuel rail . I've got a new plugs. I checked to see if I could blow through the fpr and I couldn't .
Anyone have any ideas what this could be , seriously the weathers warm and i wanna drive my e30 .
Any advice seriously any input I have some vids posted up
Im not sure if the Alternator is charging , because the lights are on the dash but it used to do this until I touched the pedal ,could that have anything to do with it ? Help me 0 miles on my motor :(

take your injectors out and have them checked and cleaned, they could be leaking/ dumping too much fuel.

I'd replace the CPS just for the hell of it. It can be intermitent and cause all sorts of problems. I had a car running rough and lean (so lean the exhaust pipes were red) and it was the CPS failing.

[e30m20TurbO7]

im already removed the injectors , and i sprayed carb cleaner on them checking for vacuum leaks and there were none

[Bmwb]

you should properly test the injectors , also when you plugged in the ICV it shut off what if its not operateing correctly or just stuck and not working check that out clean it out aswell , and your ecu isnt throwing any codes? it sounds like its an electrical issues go through all the wireing check every little thing to see if its torn , i know that mercades had a problem with similar issues were the wires would just decompose with these bmws sometimes the wires are so old the insulation crack look around find crack maybe even a tear in the wire can cause all sorts of issues

[e30m20TurbO7]

i got it diagnosed and i was told it is the TPS and the CPS , bought a cps today and im picking up and tps today from a friend

[e30m20TurbO7]

To much fuel pressure , what causes this ? Not a plugged return linen, stock injectors , 255 walbro hellp

[e30m20TurbO7]

Replaced fuel pressure regulator , and it fixed the fuel pressure issue , but now my cars running lean and won't run unles you feather the throttle it will sorta rev but not really , with the airbox and everything connected . I need some help I dont believe I have any vacuum leaks since I've checked everything and the only possible one would be the breather tube , theres no oring on the block side , any idea why my car would be running lean,

Have a smoke test run.

I put the harmonic balancer one bolt off and it was not positioned right causing ignition timing to be wrong
