Crazy Random Shutoff- FIXED!!

[dnguyen1963]

But would it really be that drastic? I mean, the car is starting just fine with new CPSs- then it will just randomly cut off. What is it about the intake that's so crucial it would make it randomly die after idling normally for a few minutes? I ask not out of flippancy, but rather a lack of knowledge... For real, I'm going to keep trying, but if I'm ever going to be able to do this stuff myself I want to understand the theory behind it... Thanks for the advice, though.

Yes, vacuum leaks can be that drastic. In my example, when the elbows came loose the car behaves like it's going to die then fire right back up again like nothing has happened.

I once had a bad ecu that would cause the car to randomly die. It would always start and run for a bit, but eventually would stall, and not restart for a while. I tossed a used ecu in, problem solved! Took the old ecu apart and found a bit of corrosion on the board.

Something to check after the basics (air, fuel, spark) are sorted out.

Also, check the idle temp switched. It can cause some issues if it isn't switching, or I'd switching at the wrong time.

I'm surprised no one else had said this yet, but save yourself some money, and get your car back from the shop.
Go buy a volt meter, a fuel pressure gauge, and a Bentley manual.
Then start working your way through the tests.

Also, since you know it needs it anyways, get a new cap and rotor.

There aren't that many places that can leak air, and between a new boot and pelican parts intake gasket package, you will have ruled out pretty much all of them in an afternoon.

One of the greatest things about the e30 is how easy it is to work on and fix.

Once again, good luck!

Yeah, I'm sourcing trailers right now. My problem is I have no garage, I have to park on the street.

I do, however, have a Bentley! Voltmeter and Fuel gauge next
