Car dies at low speed...help please I have an intermittent problem with the car in my sig dying at low speed and sometimes idle.
It will start right back up after, sometimes instantly other cranking a few moments. No codes. I have checked power wires to pcm and ground wires to the engine and all are tight and look good.
Seems most common during stopping, especially during a turn or on an incline. It doesn't fizzle out with a bad idle usually, just dies like turning the key off sometimes from a 1000rpm idle.
Problem has been getting progressively worse...I'm getting afraid to drive it out of the city limits.
Other notes possibly unrelated: the other day my tach was twiching even though idle was stable...tach was jumping up 500 rpm unnaturally
at cruise when i let off the throttle the car randomly falls in and out of closed loop/open loop and pulls timing down to 2* then puts it back in

well I think I've got it narrowed down to cam sensor, crank sensor, or the wiring for either...
these sensors are both kind of expensive and non returnable as well as being a bitch to change, what's the best way to determine which is the problem? I have EFI live
