If you connect it while engine is running, engine will die, start engine and check that you have vacuum going to MAP sensort, if you do, could be a bad MAP sensor, if no vacuum add in-take vacuum, if engine light is on, do a computer diag. where you can see MAP senor data.

It could be a combination of 2 things. A faulty MAP sensor itself or a bad TPS (throttle position sensor). It's not uncommon for a bad TPS to idle when the motor is cold but once warm, not idle fast enough to keep the vehicle running.

I need to know all the fault codes you have received on testing. I really doubt that any sensor is taking out the computer, worked this type of repair for 20+years and have never seen that happen, not once.

One possible explanation for this is that the crankshaft position sensor is going bad.

Rough running

Try checking Throttle position sensor with an ohm meter. Remove connection, put probes on pins (hit & miss on which ones, but you'll find 2 that give you a reading that increases as throttle is opened) and read meter as you open throttle all the way open & all the way back slowly & smoothly. The reading should go smooth up & down, If it jumps, or doesn't move at all in some spots, it's probably faulty. Have you tried to get any fault codes yet?

ty unplugging your MAP sensor then starting it, if that don't work plug the MAP sensor back in and try to start it. another thing to check is your cam sensor as your crank and cam sensors have to work in time with each other.
