    hi, the car has 70k on the clock, it comes from a local car sales man. he has had it a while and has had this problem since taking car in. he had new cat and oxygen senser put on it, but no change then he brought it to us. the oxygen senser does switch to start with then it stops and sits around 1v on scope, have put in another 02 senser just to rule it out in my mind. still the same. the emissions go up when the engine gets hot. have bypassed the temp senser with a varible resister setting it to different temps but doesn't make any difference. have scoped injectors and they are open for 2-3ms. have scoped the maf senser and watched it as temp rises and there is no glitchs or drop outs. the plugs in are bosch but have tried a set of ngks but no change. it has got me a bit stumped regards john
