Hi guys.
Over the last few months I have felt that my 197 isn't quite as quick as it sould be.
My downstream O2 sensor failed when I first had the car so I replaced it with a Bosch universal sensor. The 'check emissions' warning has come on again and a diagnostics unit pointed the the O2 sensor again. I don't know which one, but I guess the universal sensor just didn't work out. Could this faulty secondary o2 sensor effect the cars performance?
I should note that since I changed the o2 sensor (all codes were cleared at this time), a 'missfire' code showed up on the diag.
Basically, the car seems to pull well enough in the high end of the rev range, but the lower revs are diabolical. For example, if I slow right down for a corner in 2nd, take the corner and plant it, there is SO much lag, easily 4 seconds of really slow building revs. Like turbo lag.
Last thing I will note that the only thing I haven't inspected in my ownership is the spark plugs. I have changed my oil and filter in the last 4k, replaced a dirty paper filter with a ktec panel filter and had all my belts changed.
Any ideas?
Help appreciated. I will remind you that to the untrained eye, the car would probably seem fine. I just know its not performing to it's full potential.
