---------------------- And I thought it was hard to change the O2 sensor. Took me about 30 min. That includes jacking up the car, placing jack stands, re-wiring, (used O2 sensor for the '90 Mustang :p )etc. Next will be the easy part. Wires , cap and rotor which I have not checked the condition yet. Then we will see if the mileage will improve. :)

Any comments ?
Thanks
