I posted the other day about stalling/high idle especially when first starting after being cold. I found another 240 and confirmed that my vacuum lines are in the correct placement. Today going and coming to work, the car seemed to hesitate and not have the smooth feel it normally had. When I got home, I looked again for something out of the ordinary.....and I found it. The gray junction box on the firewall that plugs together from the wiring harness had one of the wires popped out from the plug box and must have been making an intermittent contact connection. I opened the box up and plugged and taped each together then taped the whole thing to the end of the harness on the firewall.
So far, no stalling. But.......the idle seems to be a bit high, around 900 rpm with the engine warmed up. This morning after the cold start, it was at 1500 rpm. I tried dialing the knob on the throttle body to decrease the rpm per the Haynes manual to the suggested 700 rpm, but I ended up dialing the knob until it stopped turning with just a slight drop in rpm so I turned it back up a little to where I thought it was.....I forgot to count how many times I turned it. Any thoughts? I'll find out how it drives tomorrow morning with the outside air temp at 35 degrees.
Thanks for looking. I'll roll over 377K tomorrow morning too.
