weird idle problems
ok so i got an interesting problem.... first of all i have a 1999 ford ranger 4.0l v6... i have a custom exhaust its after the cats into a flo pro muffler and has a side exit before the rear wheel with a 4 inch tip... i have replaced all 3 of the o2 sensors.
well my cel came on and the codes indicate that my right header o2 sensors heating element is fried. and its running lean on both sides... and when im sitting at idle it jumps around it goes from normal idle and jumps too 1200-1500 for a second then drops down to normal and then jumps again. it doesn't stop doing that... then when i have both dash and floor vents on it seems to idle high when its on heat. anyone have this problem????
any solutions would be very helpful so let me know
