Hi Joe, Manny and all others,

I did spend quite some time checking for vacuum leaks and bad wires/connectors. Yesterday I disconnected all connectors to ECU and sprayed all of them with contact spray. I waited for about an hour an reassembled. Now the car has lost ALL of its performance. Idle is good, hitting the throttle gives enough rpm but when under load it's awful. Today I checked cable from sensor in exhaust (labmda ?) Four wires are in a steel harness that is in a rubber harness. I checked at the place were the rubber harness shows 2 cracks, where it bends to go inside plastic cable guide. I could slide rubber and steel backwards and was able to feel the 4 wires, was able to pull a little to see if one of them was broken but they seem ok. I measured at the connector (sensor disconmnected) with an ohm meter, all combinations on the 4 wires but couldn't measure a thing. IS THAT NORMAL ?
I drove the car today, twice, for an hour, highway and noticed I somtimes have full power available, but only for a very short period after I turn the ignition key off and on.
Has any body ideas when reading this ??
Thanks again.
Nico
