M50 swap problems

[PauliusB]

I swaped M50B25 in my e30, but car didnt ran smooth, so i took off my intake manifold to change gaskets(i tought that it had vacuum leak), but after that i wasnt able to start my car, then i took out my spark plugs, and they were flooded in gasoline, after that i decided to change pulse generator, but it didint helped, but i put in one from M20B20.Maybe someone of you BMW wizards dealt with similar problem, and can help me out? :(

do you have the intake boot holes plugged, can still have a leakin before the throttle body. all stock?

Yes, all stock, hoses plugged, dont know what to do :( can this be because of bad air temperature sensor?Because i took off intake manifold earlyer(to change engine harness), put all back and everything worked fine, but this time when i took off manifold, i took off air temperature sensor to clean it, and thesse problems began

leave it unplugged try to start it, jump the 2 wires try to start, dunno

Try not just throwing parts it and follow a diagnostic flow chart that pertains to your problem or get someone who knows what they're doing to look at it.

Throwing parts at something is a waste of time and money, it also usually causes more problems because you don't know what your doing and cause issues by incorrectly installing parts or forgetting to put parts back on.

People can guess a multitude of things on any forum but you need proper diagnosis in person.

Good luck!

Yesterday we did a dignostic, and found some interesting stuff.My temperature sensor reads that temperature is -47C, and other interesting thing was, that ECU was missing +, or a good ground, thats all the errors was being shown.But the problem is i dont know what temperature to purchase, my temp sensor part number is 1709967, but i can only find one with only 1709966 part number, but bmwfans.info shows that 1709967 is bilaterally exchangeable with 1709966.So should i get 1709967 sensor?Whot do you guys think?
