I have been chasing a running problem for about two years, it felt like a fuel problem, engine had lack of power, mostly in the mornings, I would try and overtake but had now power, , even when the engine kicked down.....its was really poor, ....after giving the engine some heavy stomping on the gas pedal and making the old girl rev the power would come back in a wave as if the engine was suddenly getting fuel, ....this this has run me ragged ....so I started replaceing stuff out of desperation, it really did feel like a fuel supply problem so I replaced fuel pump, TPS, fuel filter, distributor cap and leads..... didn't think it was electrical but they looked old.....plugs.....maf, air intake pipe, air filter, .....finally a couple of weeks ago I replaced the o2 sensor...... well what do ya know, that fixed it......I had checked the ohms reading on the o2 sensor about a year ago, .....it seemed to be giving correct reading from cold and as the engine warmed up, but it's was the problem........my car was miserable some mornings....worse if it had stood a week or 2 without being used, .....o2 sensor was making it run lean, sometimes it would kick down but had no power due to how lean the o2 sensor was making the engine run,,,,,,, fuel consumption has got a bit worse but the power is back, it drives like a different car now.
I had no check engine light,
I don't know how long o2 sensors last, some car makers have them on the service list to change at 50-70k or 100k, mine might have done 190k, never changed one before but its worth keeping in mind, for 60bucks it might be worth changing every 100k , I was thinking about putting a supercharger on.....don't think I need it now my power is back.
