Evening all,
Needing some help with this as it seems to be getting worse.
The Cav SRi 8v 20SEH is running really bad. It idles rough and erratic, mpg is down, power seems to be holding back and EM Light is coming on.
It's quite odd as the EM Light will come on when you press on the throttle and when you let go, it goes off. The ignition system is new i.e. dizzy, rotor arm, leads, plugs. The engine is running on all 4 and plugs are showing that it is running ok (light brown deposit on plug). Idle control valve is now brand new, CTS is only a couple years old, battery is new.
When we do an EML flash it gives us that battery voltage is below 10v. Volt gauge shows 13.5v, got a reading across the battery terminals with the engine running and it is above 13v as well.
When I disconnect the Air flow meter engine cuts out, so I'm assuming that is running ok.
All I can think of is replacing all sensors one by one until the problem has been resolved but I need ideas to work out a process of elimiation. Earth strap next to alternator looks fine and gear box one is still ok by the looks of it too.
I am stumped!
