I am in need of help. I have a 88 740 B230F engine with the EZ-K 117 ingnition system, you know ,with the Hall Senser inside the distributor cap. Anyway it idles rough and when you put it in drive it stalls out unless you run it at around 1500rpm, and it will bearly move at that. I have spark at all spark plug terminals and the injectors are clicking away ( I used a sethascope ). I pulled off #4 at the most rear of the engine and there was no difference at all the way the engine idled and did the same to #3 and got the same result even though I have spark. When I did this to #1 & #2 ( one at a time then reconnected each one spark plug wire back to the plug ) the engine stalled out right away. This all happend at once while driving home. WORK Done: Replaced ign. coil readings were out of specks Replaced timing belt and tendtioner pully, Replaced FPR valve, replaced fuel pump relay, Cleaned throttel body and amm Checked all the electrical Wires and Grounds Checked for any cracks in the air intake hose- none found, IAV works fine, knock senser check fine, Used electric grease after checking each connection, New dis cap & rotor, wires. Checked fuel pumps- in tank pump not working. I am very TIRED now. Has this happened to you ? Do you think it is the Power Stage ? Or the Radio Surprestion Relay? Please Help, as you can see I need it. Thanks Dan.
