Well its been a long road getting The Blue Pig on the road. With the help of this forum I have solved a ton of issues, so thank you all for that. Hopefully I have documented my threads well enough so that others can learn from them.
Anyhow, I have her inspected and moving down the road, but the engine just is not as happy as I would like it to be. It starts just fine every time, so no issues there. When it first idles, it is at about 1100 and drops to 800 or so when it is warmed up. What I do have trouble with is a jumpy/jerky throttle and what feels like a pulsation on acceleration. There is also a fair amount of pinging.
Here are some notes:
- All new vacuum hoses everywhere
- New Map sensor
- All new fuel system except fuel regulator and injectors
- Lubed the throttle cable
- Did zip-tie mod to take up slack in stretched cable.
Thoughts on where to begin? I am not a total noob, but my diagnostic skills are still in their infancy. Could it be a misfire? Fuel issue? Vacuum issue?
