Service Engine light Low power

[Marv02]

This is the skinny With my 2001 EX EB with 5.4 It started out as a Coolent Leak end up being a bad Intake manifold that was spraying water on the Righ rear Coil pack.

I replaced the Intake checked al the heater hose for leaks checked good so I reused them, New Plugs New coild packs Cleaned ICV.

I still have a rough Idel not super rough but not normaly smouth There No Lowend Power very lazy I tryed to reset the computer still no luck I getting a service engine soon light.

I will get a code reader this comming weekend.

Any Idea's what could be the isuues.

When the car stated acting up I drove it 30 miles to get it home before this It ran great back then this is before I changed out the intake and the other stuff.

Is It possible the O2 went bad when I limp it home during the 30 mile to get it home.

You need to pull the codes. Anything else is just guess work.

Coil Pack

When down to the local Napa and used there code reader it showed code
P0353 Bad Coil Pack but they are all new then again new dont mean it's good LOL.

So I swapped one at a time the #6 col pack was bad.

Runs great now.

Took the Ex for a 40 mile drive so far Good no leaks runs Great and my MPG went up.

I had a 1999 EX EB 4X4 it got 16 17 MPG so when I got this 2001 EX EB.
I was thinking it should get about the same or better due to it beening 4X2 less weight to pull around.

To my suprize it only was getting 13.1 Avg Now I getting 16+ I can live with that.

Suprize what a tune up will due.
