Hi y'all,

I'm a newby here to the forum and am looking for some help. My 700 xp I bought used has been a nightmare from day one. So far within the past three months of ownership I have replaced the tbap harness, fuel pump, dipstick tube, new stock exhaust, air precleaners/filter, and of course a oil change. Now for my problem. The exhaust manifold is glowing red after a few minutes of easy riding. I checked fuel pressure since I've already been down that path.. But was a steady 39psi loaded up or easy riding. Next thought was the boot from the throttle body to the head but I couldn't find a crack. Any ideas as to what the problem could be?

Thanks!

Have you checked the TPS setting? Have you checked for codes?

No codes except for the occasional 25. And no not yet. I have heard and seen way to many things such as "Just move the sensor and listen" what is the best way to test it? I have a decent voltmeter.

The tps testing procedure is in a sticky in the Ranger technical section. I'd use that.
