Fuel query for a car

SOURCE: How to improve the fuel efficiency?

Consider getting this info on ADDING Hydrogen power to your fuel. Raises fuel mileage 25% to 50%+.

Imagine if it works - raise your fuel mileage to 21+ in stop n go driving, up tp 35+, maybe 40 mpg with a steady low cruise on the highway, at 60-62 mph.

only costs $170-$200 if you can do it yourself, if you can change pcv / oxygen sensors / plugs / fuel filters, YOU can do it.
Else, pay a mechanic an extra $200 for 2 hours work for him/her to install in 45 minutes.

You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.

The reason it's stalling out is because of the adjustments you made to the CAS and TPS. You need to reset the CAS where it was, since when you rotate this sensor, you change the ignition timing. As for the TPS, that also needs to be reset to how it was. The way to adjust the idle on this engine is with a screw on the idle air control valve (IACV). At the back corner of the engine, on top on the driver's side, the IACV is bolted on. If you crouch down next to the driver's fender and look straight in at the IACV (with a flashlight) you will see a screw recessed in there, with the head pointing toward you. That's the idle adjustment screw. With the engine running, AFTER you have reset the CAS and TPS, turn this screw until you are able to set a warm-engine idle of roughly 750 RPM. Messing with TPS voltage and ignition timing is a sure-fire way to stall or blow up your engine.

I had a similar problem with my jumbuck,2 sets of keys only one worked. Replaced battery now ok.CR2032 ,tednanango

SOURCE: no power rough idle car stalls strong exhaust smell

have you done a reaaly good tune up on the car? I would suggest replaceing the idle air control valve first, the a really good set of plugs and wires. I would also reccomend that you check the fuel regulator to be certain it is getting the required vacum to operate the release valve and let the fuel flow back into the tank.
