Hi list, here i am again Well I had a MAJOR stalling when warm problem, so after reading the codes ( advise of mr stern..thx!) I got o2 sensor codes ( 21/52 ) and I replaced the sensor. The codes are now gone, and the problem is less fierce. But.. i still get a stalling after a drive of 20 mins. The car doesnt'die and i replaced the following; -rotor -ignition wires -sparkplugs -fuelfilter -airfilter When the car is running idle the rpm goes up and down 30 rpm continues. When revving up a bit it takes quite some time to get rpm back to idle ( a sec or 2 - rough guess) Any suggestions what to look for now?? Thx a mil Guido
