Hi all.</P>
<P>I have a strange problem with my 1996 K1500 5.0.</P>
<P>Intermittently the idle speed will raise to 1500 rpm and stay their.</P>
<P>This has been ongoing for some time. Items done after this started.</P>
<P>Converted to mfi, had leaking regulator.</P>
<P>egr valve replaced. had pintle position code.</P>
<P>intake gaskets replaced due to leaking at rear.</P>
<P>swapped iac, tps, crank sensor, has no intake leaks. has new plugs, wires, cap, rotor, fuel pressure per s.m. 58 psi at idle. koeo pressure is 65 psi.</P>
<P>driving pressure is between 58 to 63.</P>
<P>Any one seen this problem?</P>
<P>Thanks</P>
<P>Dale</P>
throttle is not sticking, throttle plate is fully closed.
