brokebill Posted July 16, 2008 Share Posted July 16, 2008 86 GL, 2wd, 5spd, hitachi carbed wagon i know how pointless it is to troubleshoot a feedback hitachi, but i've noticed when coasting down a mountain in neutral that when i take a left turn (counterclockwise) the idle will drift up a couple hundred rpm and when taking a right hand curve (clockwise) the idle will drop a couple hundred rpm. is this characteristic of anything in particular? (float sticking, something on the tank side of things, etc.) i know, its a feedback hitachi, but i know lots of yall have vigorously and stubbornly studied and troubleshot these things before you washed your hands of them in favor of webers and fuel injection. appreciate your knowledge on the subject. thanks, Bill Quote Link to comment Share on other sites More sharing options...

I think it would be well worth the time. I'm due for a trip anyway. Lemme know, I get most of the week off. And to answer your question, I have no idea.

94Loyale Posted July 19, 2008 Share Posted July 19, 2008 Well, I have no experience with the Hitachi's at all. But I had problems similar to that with Rochester 2 jet's (on some of my previous GM products ) It was always the floats on them. I'm sure someone with some valuable info will chime in though,haha.

GeneralDisorder Posted July 19, 2008 Share Posted July 19, 2008 Probably just needs the float adjusted. There's a sight glass on the side of the float bowl - it should be right in the middle. Could be low fuel pressure also but as they run around 2 psi it's hard to get a good reading on it without a decent gauge. Cheap gauges just aren't accurate at low pressure's like that.

flight_of_pain Posted July 19, 2008 Share Posted July 19, 2008 LOL, i have the exact opposite problem on a feedback sedan. when i turn left it drops rpm, if a make a sharp enough left turn with it in neutral i can actually kill it. isaac Quote Link to comment Share on other sites More sharing options...
subyfreak Posted September 29, 2008 Share Posted September 29, 2008 same problem with the EA81 transplant in my 87 GL Turbo 3dr. Unsure of the year but does the same thing. After it stalls out it is a real pain to start back up. Anyone else have this problem and know what it is? Quote Link to comment Share on other sites More sharing options...
