Hey all,
This summer my car has been kind of hesitating from
take-off, not real bad, just kinda flat for the first bit, then ran
fine. Last Friday night at our local cruise, it started hesitating quite
a bit more, and not wanting to idle at stops while in gear. Took it out
on the highway to "clean it out" a bit and it acted like it was at half
throttle at best. So, tonight I changed the fuel filter, it was bad, and
took it out for a ride. Ran pretty good at first, but after a while, the rough
idle was back and so was the hesitation. Increased the idle speed a bit,
and the accelerator pump stroke as well. Same. Also, if you rev it
up a bit in neutral, it takes a minute or so for the RPMs to go down to
idle speed. Linkage is not sticking, as even holding the throttle lever
closed doesn't make it slow down any faster, you just have to wait for
it. At say 1500 rpm in low, you can hammer it and it responds nicely. It
will also downshift and accelerate fine when floor boarded. Seems to
just be low rpm related.
Only change I have made to it was putting on a
Mopar electronic ignition system. Starts wonderfully with it btw.
It is not a kit, but all parts I found in my "stash". Distributor and
control box are very low mileage though, I'd say 1000 miles or so, although
they are probably 20 years old. Also, I haven't done any "tuning" to the
igition yet, due to the rough running which I have been thinking was all carb
probs, so it's only at 5 degree advanced at this point.
Here's the
particulars
68 383 HP, stock except for "Purple Shaft" cam
Edelbrock
800 AVS (5 or 6 years old)
Dual exhaust off manifolds
Mopar
electronic ignition with orange box
Automatic with stock convertor
Fresh
premium gas
Any thoughts? Always put stabil in the gas for
storage, but carb might be getting gunky inside? Could ignition timing
be part of it?
