2005 LR3 wont accelerate

[pastureboy]

I just hit 141,000 miles on my 2005 LR3 and today when I tried to drive it it started with a rough idle then would not accelerate at all. Any ideas? It just got towed and is on the way to the dealership.

Your post is a bit vague and that makes it tough to help you. Do you mean ABSOLUTELY will not accelerate? If so I don't know what that is but it sounds major. If you mean struggles to accelerate then that + the rough idle could be: MAF Sensor, dirty throttle body, EGR Valve, or thermostat.

Prob the gas pedal or throttle body see if it opens when you press the gas pedal or listen at the very least

I took it to get checked out. Turned out I just needed to clean out the engine from using low grade gas.

Low grade? You mean low octane?
