BMW E30 throttle position switch repair TPS

[@dohc1974]

Is it possible for the idle switch to go bad somehow, what’s inside that switch? Maybe just some more contacts with more solder fail points. The full throttle contacts seem like they can be fixed with new solder based on your findings.

Before u did the repair how was the car running ? im trying to diagnose if this switch is my problem, The car will start up fine but wont idle i can sit there and rev it to keep it going everything mechanically sounds normal but wen i really get higher rpms starts to get really rich , and before this randomly happened the car ran flawless for 2 years no issues with anything

@@eddieguillen2102 I just got the car back from someone i took it to, after i replaced the TPS and a couple of thermostat housing sensors he replaced the crank sensor to see if that was the problem and that didnt fix it but realized that sensor was only receiving a couple of volts when it should of been getting more so in my case it was that certain part of the wire harness that was supplying that area which was no good . So it could be the harness not giving certain sensors the right amount of power to work with . its hard to tell because it can be so many different things fucking it up , its a nightmare im lucky he found that out

You adjusted the idle screw?

lsospechaba lo que me acabas de confirmar, despues de un par de mediciones y pruebas.... la pregunta es... ¿ porqué este componente cuesta esa cantidad absurda ?
