Now I've got to speak up and my twists to this situation.( OK ) I've been monitoring this thread because I have similar issues after my 30k miles service, and leaning my car out. I've probably leaned it out tooo much, but I was trying to find out why I only get 15 city mpg; how hard I drive makes almost no difference. ( Typically, The 02 setting can be adjusted when running to rich to compensate for the 02 sensor age.It should be changed out at the 30,000 mile mark or sooner if it's been abused by over enrichment.) But, if your warm up reg ( cpr ) is not putting the pressure on the top of the control plunger in the fuel distributor, then your trying to adjust one to compensate for the other. Meaning you can't adjust the 02 to make up for the CPR pressure. I would replace the CPR and the 02 sensor then readjust and you should be back up to the 21 MPG +. Results to me based on what were talking about you would run to rich.) Early morning or four hour parked starts smell very gassy and run rough, almost bad timing-like. I did have a bad vacuum hose on the timing advance unit, but that is fixed. I'm thinking something else is losing vacuum and it takes time to build it back up after starting? Say the system loses vacuum-- how long does it take the system to get it back up? And if you lose vacuum in one part, does it effect other parts, like the air mode switch? ( Dave may have a better handle on the vacuum build up, but I would think it's instant or a second or two.) Hmmm, reminds me that last summer I had starting issues if the car had been sitting in the hot sun for all day. Never did solve that, it just became less of an issuel. Is that the fuel accumulator? Could that be working in tandem or is that my real problem? ( Was this a hot start problem.)If so then you know accumulator and new O rings in the distributor will normally stop that.)In the hot sun if the coolant temperature doesn't go down below 95 degrees the TTS switch won't let the CSV( cold start valve ) fire off when you try to start the car. Coolant is to hot.) Where as at night and in the morning it may. John hervey www.specialTauto.com
