Cutting out WOT and other symptoms
Haven't had much to complain about on this low mileage (34K) 2001 MGM LS. but I did notice recently that it may be bucking slightly during steady cruise,very lightly and occasionally.
Then more recently I noticed in the AM on start-up I had to give it a slight amount of gas peddle to get a smooth idle.
Then yesterday I floored it just for fun from a stop and it was cutting out or losing power badly. Run-off-ruuuuuun-offffff-ruunnnnn etc. I don't think it was completely cutting off but it could have been numerous cylinders.
I have recently replaced the fuel filter (on schedule at 30K) with a Fram. Also the air filter. Everything else is original.
No CEL displayed.
I started it up just now to see if there was some sort of delayed CEL or something and it started right up from 57 degrees (F) with only a few shudders in the first 30 seconds or so then a nice smooth idle.
What should I be checking? Auto Zone won't run codes in Calif BTW, some legal problem. Much Thanks- Brian
----Update: Drove it around today city traffic and it occasionally has a single miss on acceleration or while steady (a little bucking) but acceleration pretty good. Once I stomped it while going maybe 35 and there was no change for about 1 1/2 seconds then it reacted and finally downshifted. Thanks-Brian---
