Service Engine light Low power

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.

To reset the ECU just disconnect the battery for a couple of minutes.
As for low power, I suggest that you check all of your vacuum and electrical connections as well as spraying some WD40 all around the intake as you may have a sealing issue.

Thanks but I already done that.

The funny thing after I got the Ex running again after it sitting for the last month and driving my 435 H/P vett every day I knew the EX will be slow compaired to the Vett.

But it was not that low on power I drove the Ex for a bit hoping once the ECU reset it self the under power issue would clear it self up.

As normal my luck it did not help.

I want to start driving my smouth riding quite comfy Ex.

The Loud rough riding fast vett fun but it gets old but the put you in the seat power sure is nice on tap.

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.
