535i dies, then is fine, what the H!!!

Hi, I just bought a 535i 1989 and on the way home it suddenly lost all power and just idled. I turned the car and the turned it back on and it ran fine. The engine light had turned on and then it turned off when I turned the car on.
It did it again today. I would push the gas pedal down and it ran horrible. So I turned it off and it ran fine.

Any ideas?

Hey Andy. With that scenario, it could be so many things. Guessing and buying random parts could get extremely expensive.

The first thing you need to do is get the codes read (I don't think you can do the stomp test on your car). Let us know what codes are stored and we can help you go from there.

Most problems are usually something simple !

Sounds like a electrical connection loose or failing.First I would check connection of battery. the ECU connections . Then to the supply cables under the main relay area. A bad coil may be it too.

Check your grounds, check your MAF, check your plugs, check your air filter, check your fuel filter and check your fuel pressure/fuel pump sending volume.

The throttle position sensor. I'll bet on it. And really, don't drive this car. The engine could cut on you at any time.

One way you could fix this (if it is the tps) is to remove the tps switch, use contact cleaner on both the tps and the switch, then apply some dielectric grease to the switch and plug it right back. Then take the car out for a drive where you won't run into problems or cause problems if the engine suddenly cuts out on you.

Before doing all this, see if you can recreate the problem with the car being stationary. Maybe if it idles for 10 minutes it will cut off by itself. Or maybe it needs to be revved for 5 minutes consistently, etc. You get the picture.

Please let us know how it goes.
