Re: 95 Chevy S-10 4.3L TBI - Idle troubles
hello qldit,
Yes, the computer is were I am going. I have checked the 5v reference voltage from the computer and it is ok. I did replace both injectors with two identical replacement parts from autozone. Well really three of them. One of the first two was stuck ON. It would flow fuel just by turning the key ON and without the connector being plugged in. I took it back and got another one. Yes, it should be self correcting and with one injector plugged in I am getting a msec timing pulse of 3.8msecs. The engine is lean, but it is close to right. When I plug in the second one the pulse width only drops to about 3.1 or so. this goes to both injectors. It seems to me that if one is almost good ( for idle ) at 3.8 then two would drop it down to around maybe 2.0 for a combined effort of about 4.0 worth of fuel. Anyway, I am going to find a way to get the computer out from behind and above the glove box and I will remove the cover a see if it looks bad and I will more than likely replace it anyway. I don't think I have any choice. I am already out about $300 what a little more? I will post again. Thanks.
