Hi, all. I fixed my electrical demons a couple weeks back with help from you guys (and a little bit of searching old forums). This place is always a big help.
Anyways my 69 Malibu convertible 350 is acting up again. It's a 2GV carb, and the throttle won't open enough.
When I was poking around fixing electrical bugs a couple weeks ago I noticed the throttle cable was getting old. When I was out driving it earlier this week the gas pedal suddenly didn't want to move. I could maintain about 35 MPH smooth enough, but the pedal just wouldn't push any further. Figuring that old throttle cable might be the culprit, I put a new one on.
I had a '68 Malibu years ago that snapped the cable in the passing lane on I-75. That was hairy. I had to play Frogger with no acceleration, coasting three lanes between speeding cars to the right berm so I could rig it up and make it in to work. Fortunately I worked at a Chevy dealer who had the cable in stock. That memory and the condition of the present cable convinced me to just replace it.
Well, that didn't solve a thing, except that I no longer have to worry about snapping a cable soon.
I was playing around with it tonight, disconnecting and reconnecting stuff. Tried it with and without the cable connected, but when I took the accelerator pump rod off the throttle linkage it opened wide.
Could my accelerator pump be stuck? That rod only pushes up a small bit.
