Do it before you drive it again. Better too loose than tight. Too loose won't harm anything but your ego. Too tight makes your check book open.

Do it before you drive it again. Better too loose than tight. Too loose won't harm anything but your ego. Too tight makes your check book open. +1 .... (IMG:style_emoticons/default/smash.gif) OK, I have readjusted the rocker arms again, checked the timing, etc., and it still will not idle without "butterflying" the throttle. What next? I have pulled the plugs, they are clean and gapped. Checked all the hoses and connections, again. Should I test the AAR/Throttlebody readings? Is there anything else that would affect the air/fuel/idle ratio? It runs well when accelerated, but will not stay consistent after a few moments at higher RPM. I have a Petronix unit. I pulled the distributor and checked the gap from the pickup to the magnet...it is at .003, as the manufacturer recommends. I am not Mr Goodwrench, but I have been tinkering with VW/Porsche 914s since my teenage years... 69VW being my first car, 74 2.0 my second. Is this when engine is cold? Could be stuck closed AAR. My AAR had the exact opposite at cold start....idles up around 1800 until then warmed up and then goes to 3000 RPM because the AAR doesn't close (stuck open). I've got a new refurb one to install, but my short term workaround every morning has been to get out and plug the input to the aair vac line (after which idle immiediately drops to 950). Voila!! |
