4. cam belt slipped do to no service, (or chain on cam)
5. Low fuel pressure
6. or too much fuel pressure ,floods or rich misfires.
7. misfire. causes low power ., lots of causes. over 50, in fact.
8. The CLuster Check engine light on? running?
9. Scan the PCM yet to see if it has DTCs; errors to report?

there are steps or tests in each case.
why not get the car serviced. they will do those tests.

You need to diagnose any codes you get
& smoke test the evap system, to find a
problem

Seldom does throwing on parts with a name similar
to a code work

Codes have nothing to do with installing parts

Clearing codes, clears all data needed to diagnose
the failed system & the evap system only runs every few
days,so you done as far as codes helping

One of the problems that trigger a check engine light is either a faulty gas cap, gas cap not on all the way or no gas cap. Once you replace the gas cap you should be able to reset your check engine light or it may automatically adjust itself.

some times light wont reset self got to have it shut off autozone want shut it off but most advance auto will or disconect pos. battery cable for 30 min. it will normaly reset light

It should reset itself within 3-4 days. If not, ask any auto parts store to reset it and they typically do it for free.

Once you tighten the gas cap the engine light will reset itself after it has gone threw the necessary drive cycles, but only if the problem has been fixed. So yes if the check engine light came on for the reason of a loose gas cap, once you tighten it it will go off on its own.

If the engines are Zetec DOHC 16v, I would suggest that you source a new water pump for your engine. To change the water pump is not very easy for the average DIY. I would entrust the job to a vehcile technician and get the drive belts changed at the same time as the anti freeze would have contaminated your drive belts.
