ok after doing all this stuff.
fuel filter, TSB for isolator bolts, plugs , wires, DPFE .
I found the IMRC actuator rods were off because of the $7.00 ea. gromets, one was missing, got it at the junk yard for free.
fixed that,still ran crappy,
and I got a P1121
so I cleaned the MAF, to no avail,
went back to the junk yard, got a MAF there for $22.00, put it in after cleaning it and the vehicle runs great.
Moral: I think I would check the MAF first, clean it with non residue electric cleaner ( radio shack 8 oz can $10.00 )
if that don't fix it, try the junk yard for the MAF FIRST !
they want $135.00 plus a core charge of $70.00 at the parts stores.
