Problems after replacing heater hose

[sewlow]

Anti-freeze is Glycol. Get's sticky when it dries. Moisture in the cap is never a good thing. If a good cleaning doesn't get all the anti-freeze out, replace the cap, coil & rotor.

Glycol is some nasty stuff and can cause some annoyingly hard to find problems. Since it only does it during the first few seconds after starting up and then runs smooth I am thinking it has something to do with the advance hardware inside the dizzy. The glycol could have it all gummed up and from my understanding start-up is the main reason for a ignition advance on the dizzy. Can anyone confirm this?

advance is controlled by PCM with TBI...

Ah, shows how much I know about TBI. I though they used a standard HEI dizzy with the vacuum advance.

Hey, when all else fails I can get people to laugh.

Haven't been able to work on the truck because I went out of town, but the mechanic I usually work with said the problem was probably from the distributor cap getting all wet.

I ran the codes and the only one I got back was 33 MAP sensor circuit high(low vacum)
