I have a 2006 RTL with 298K miles. I have done regular timing belt changes, oil changes, it is well maintained. Yesterday the truck started to develop a rough idle. Would not start, but finally did after about 5 or 6 attempts. After it started it had a rough idle still, would run fine above 1200 RPMs, stayed this way for about 4 restarts. When started the 5th time it developed a definite miss at the tailpipe. Pull plugs on motor, had normal wear with no signs of problem, plugs had over 96k miles so I gone ahead and changed them. Restarted same issues. Tried to restart again and it would not start this time. The fuel pump starts and cycles ok, battery is new. if driven in this condition the VTM light will come on. Seems to be a problem with the idle circuit or timing control. HELP!!!
