double check the timing belt, look for missing/misplaced vacuum/pcv/vapor/IACV hoses, compression and maybe leakdown test, vacuum gauge test, confirm spark at each plug...
lots of stuff
probably suspect hoses, coil, wires and TB first - easiest for DIY I guess.
search here for specific help with those items.
post precise Pxxxx codes if possible.

I guess I should have mention that he replaced the plugs, wires, timing belts and put a new water pump on. And the car idles fine its just when its under a load that it hesitates. I'm not sure the last time the fuel filter was replaced so that might b one problem. As far as specific codes im not sure
did he test drive it?
What was done immediately before the problem started? any mods,wrecks or more repairs?
A timing belt could still have slipped. Did he use OEM plug wires? many people have problems with typical aftermarket wires. And sometimes hoses can work loose after major mechanical work.

that's where i would start.
the flashing CEL on hills is the 2 cylinders mis-firing. no 4 cylinder engine will have any power when half of the cylinders are not firing.
i would also swap the plug wires from the passenger side, cyl 1 & 3, to the driver side. see if that changes any thing. (this may be hard to do if the coil is off center, can't remember.)
but before i unbolt anything else, check the timing. 3 bolts on one side and a rubber plug on the other. you may need a flash light and a mirror to see in the ''hole''.
cylinders 1 & 3 share a fuel rail, and cams. it isn't coil related. that would cause trouble with either the front, 1 & 2, or the rear, 3 & 4.

maybe someone could recommend a mechanic in your area that would help you pin down where the problem is.
