Exhaust pressure Valve question EPV

[BobQ]

When my truck is cold and I drive it away, the EPV opens and closes about every 30-60 seconds, is this normal? It does stop when warm. I was thinking it should stay steady? I cleaned the tube and valve and have no codes. Any suggestions?

Thanks Bob

At idle, mine would do the open close open close routine before finally closing. My tube was new, so that wasn't the issue. I eventually deleted the EBPV, cause I hated it.

agree, mine does the same thing, but I aint gonna take it out cause it gets darn cold here and would suck wamin up not having it.

Mine warms up just as fast as without it, even at idle. If there is any difference, I couldn't notice.

the ebpv will open when rpm's get above 2000 rpms and when you slow back down it will again close, perfectly normal and it is working as it was designed.

like the other guy said. gut it your truck will warm up just fine without it. i had no probs in the cold the other day(it was about 30) fired right up and went into high idle a min later no prob.

Great, thanks for the answers, I thought I was loosing my mind! That is the craziest thing I have ever seen. I will search for some delete kits.

Thanks Bob

How about at -30 degrees? I'm being serious too, as I routinely work in North Dakota and during the winter it's colder than a witches tit over there!

Nobody sells a delete kit (that I know of), but you can DIY fairly easy. It's even easier if you know how to weld.

Dunno, never had it that cold. Only 0*ish.
