Ba lump Ba Lump Ba Lump...
...is what my truck started doing yesterday morning. Only when it is very cold in the morning. I started it as usual. Cranked right up but instead of the rough cold idle I normally get I got the loping that lasted a few minutes. I took off towards work and pushed the choke in. the Revs lowered as usual but still loped. then all of the sudden, it was running as smooth as butter.
i have a known exhaust leak - although i can't tell where it's coming from.
i just advanced my timing some more a few days ago (no spark knock).
Any ideas, distibutor-plugs-wires-exhaust/intake leak?
thanks in advance!
