Dont want to go up a hill Code P0302
Hi guys: I have 2000 Ford Expedition 5.4 4WD XLT. Since few months my baby has some problem to run specially when up a hill and she dont wants to go. I did research about that code and found that information on internet.
1. Faulty spark plug or wire
2. Faulty coil (pack)
3. Faulty oxygen sensor(s)
4. Faulty fuel injector
5. Burned exhaust valve
6. Faulty catalytic converter(s)
7. Running out of fuel
8. Poor compression
9. Defective computer
First I save some money and went to the mechanic and did change number 1, 2, 4 and option 3 he change the O2 sensors on driver side passenger sides were hard so he told me to put the WD40 for atleast a week and then come back to chage the rest of the two passenger side O2 sensors.
My baby still has the same problem. It runs very good when it cold but once it warms up it has hesitation which i think called misfire. Compression test when motor was cold was 130 on cylinder 2. One of my friend did the same test but the motor was hot and it was 180 on number 2 and 181 on number 1. It has the same code all the time P0302
PLEASE HELP

Dont know how many miles you have on your Expedition but I have a 2000 Exp EB 4X4 with only 91000 miles. My plugs are fairly new as I had a spark plug blow out with 84000 miles. I had the heads repaired, spent alot of money on it but thats what you do when you love your truck. I have been having an intermittant misfire on No.4 cylinder (PO304). I took the advice of this forum and ordered a new set of COP on Ebay from Uneek and installed them in a couple hours. Problem solved, no more misfire.

Hey readcit, try this link http://cgi.ebay.com/ebaymotors/NEW-I...Q5fAccessories
The COP is the coil itself, they come with new boots. Fairly easy job to replace.
I bought my "Coil-On-Plug" from them and they have worked well, they even come with a lifetime warranty, all for under $100. You cant beat that today.
