A bit down on power

[knight]

I have noticed the last few times I have driven the car that it seems to be down on power when accelerating, no obvious hesitation, just doesn't seem to be as lively. Car was last serviced at the end of last year and hasn't done many miles since.

Anyone have any suggestions as to what to look at first? The car is a 97 4.2.

This is oftern the first sign I get of a Lambda going lazy, a few days later the MIL lights starts to come on and I take it to get it replaced.

I will concur.

The lambdas and adaptives aren't used at WOT are they?
