190E 2.5-16 wont start when warm ????
 

My 1991 2.5-16 starts perfectly from cold but if i turn it off after starting, it wont start again. it matters not how long it was running for. I can get it started again with a little squirt of easystart. However once running it is reluctant to rev on anything more that a very light throttle.
Any ideas ?

Could be bad temp sensor...
Bad O2
Bad KE control unit..

Sounds like once the car goes into open loop, regulated the mapping is wrong.. So it's either a bad input or an incorrect processing of said input.

OF course make sure that the secondary ignition system is in good shape. THEN...

I would start with a basic fuel pressure test.
The CIS fuel injection system is all about the difference of system pressure & lower chamber pressures.

I would Hope a 2.5 16V would be Very well maintained @ this point...ya know?;-)

You might also check your voltage @ the EHA once warm..
