Re: throttle body
well, trying to answer your question,s
Today I started it again, miss seems to be getting worse. It constantly is searching for proper idle speed. Idles around 700 to 1000, some kind of noise in the engine that seems to change as it does so. It will idle ok as soon as I start it, however if I try to go it hesitates and dies till slightly warmer.
Volt meter on battery constantly watching it, starts out ok. About 12.40 at idle, went to 12.70 around 1500 rpm. Then started running rough and volt meter showing 11.78 or so. Put lead on back of alternator and shows 13.20. back to battery 11.80.
Seems to be some kind of electrical drag on battery, almost as if starter is hung. It is not but same kind of draw down. Weird.
I am guessing without the GS911 I will never find what is going on.
Can the Hall Mark sensor get faulty and draw volts down like I am experiencing? I do not know if it was ever adjusted. I do know that when I had my melt down a wire to the Hallmark burned the worse.
I understand what you mean about setting either the tps or the potentiometer, definitely need it on computer to do so.
Seems as if whatever is going on it is fixing to reveal itself by failing.
Tonight I will pull plug wires while running and check for effect.
Not sure about the cat code plug
Did pull wires one at a time, number one no change, others drastic change.Good spark thru wire and good spark at plug when grounded against frame. Gotta be an injector problem I am guessing as compression test showed ok.
Number one plug was worst and number one cylinder pumped up a little slower than others but not by much.
Thank you for input
