99 TJ problem

Here is
what I have going on. 1999 Jeep Wrangler Sahara 4.0L 6cyl auto
170,000mi. I get check engine light stays on with codes P0300, P0302,
P0304, P0305, P0306 only if I drive ~70mph+. I can delete codes & if I
stay under that speed range my check engine light won't be triggered.
It runs great w/o stalling or skipping. Let me know what you think
when you get a chance. Thanks.

August 2010: 2 oxygen sensors, crank sensor, new spark plugs, new
wires, new coil
February 2011: Refurbished Cylinder Head Odessa, new timing chain

'08 D. Yellow 2 dr 6 spd Rubi Hdtp. "The Mistress"
RR winch bumper w/ hoop
12,500 lb winch
Deadweight rear seat removed

Sounds like you may have multiple issues, I recommend spending the money and having a dealer work on this. I have done the throw money at the problem and still have a CEL. Its expensive and no fun!

A code P0300 may mean that one or more of the following has happened:

Quote:
Faulty spark plugs or wires
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector(s)
Burned exhaust valve
Faulty catalytic converter(s)
Stuck/blocked EGR valve / passages
Faulty camshaft position sensor
Defective computer
