Ok payday is Friday, so I'm going in tomorrow to make an appt. at the Dealer. The phantom stall had dissappeared so I thought. In the last 24 hrs though it has stalled 3 times while in park, and 4 times while cruising down the road slowly, usually shortly after taking off from a light etc.
Latest behaviour:
1 ) Very rough idle upon starting (starts up easily though first time, every time)
2 ) Idles normally for first 30 seconds of startup, and then the needle dips dramatically a few times before it just stalls.
3 ) When this happens if I press the gas gently it will more or less smoothen out the idle.
4 ) Once it decides to idle normally and I take off slowly thru the underground garage and into the street, its as though it has a very subtle surge going because I can get out of the garage , into the street and down to the light easily without ever hitting the gas pedal!
5 ) Once I am off though and the truck has settled down (5 mins or less) it seems to run like a top. Only problems seem to be upon starting from cold.
A few perhaps unrelated details I'll mention:
1 ) My accelerator linkage (engine side) seems to have some slack in it. As it lays at rest it has a slight sag downwards. If I lift up on the wire it will easily travel a 1/4" before actually affecting the throttle.
2 ) The purge line from the emissions canistor is pretty loose at the engine. By moving the line I can easily twist the connection at the engine. In fact , with the engine off, I was able to just pull the line right off the engine without any problem.
So only a problem on recent cold starts ... and then followed by a slight consistent surge for a few blocks.
TY
