Hi everybody. I have a weird problem with my FI: - the engine starts up immediately, even after one night rest; - however, it idles rough; I finally learnt that of the of the cylinders does not work at all (random, sometimes #4, sometimes #2, sometimes...), even though they all would work properly at higher rpm; - also, at idle, if I let to much air by adjusting the screw on the air intake case, I got only #3 and #4 running! I suspected that the injectors clogged. I poured an aditive in the gas tank. No change. Fuel pressure is 2.1 bars. I mounted brand new injectors ( BOSCH 0 280 150 105). No change. I re-re-rechecked the wiring, suspecting some bad grounds. All was OK. Throttle switch and pressure sensor OK too. I verified the compression. With cold engine, I got some nice values, in the range 8.5-9.5 bar, 'cause 3 weeks ago I mounted new german rings (Schotle Motorenteile) and grinded the valves and the seats). Finally, I ran out of ideas. Could anyone provide me with a piece of advice? I don't realy want to install carbies (SOLEX 32 PDSIT 2/3)... Bogdan KUCINSCHI '71 Squareback
