All that was done (entry to left) well under power the Formula is no good. Timing was set per lable under hood and looked good on the road no power had to set timing approx 20 degrees prior to tdc to get power now I suspect gas will wash doen cylinders and cause other problems. Timing Chain off a bit? Possible cam wore?

Your engine computer will set the timing as you drive your car. The computer has full control of the timing and monitors it constantly, adjusting it as you drive to get the best performance and gas mileage from your engine. If you have an older car.....you need a timing light....a special 90 degree closed end wrench...I think 1/2" or 9/16".....and a helper to tell you when the marks line up using the timing light.....ohh yeah....you spin the distributer left or right to advance or retard the timing. when the marks are in alignment on your fly wheel and the gauge marker under the timing light....turn off the engine....tighten the distributer hold down bolt, (located under the distributer cap), back tight to hold the distributer haft in place.....then your done..good luck and always work and play safe.
poor pick-up and less miles per gallon after engine head repaired is due to two things could be done wrong during repair,
1: wrong tappets clearance, witch is suppose to be 0.30 MM inlet, 0.40 MM exhaust
2. wrong timing setting ( timing belt setting )
better to get your mechanics to double check it
ok/theres fuse box left side /drivers side part of dash i looks like a tiangle it pops of /look for accs.fuse they r labled .if not there then under hood left side top pops off all labled/i dought it though people could break in if they can pop hood.
Locate the timing scale located beside the crankshaft pulley. The "T" or "0" represents Top Dead Center. The plate is scaled in one or two degree increments and should have the correct timing marked for your particular car. If not you will have to count to the correct degrees, which will be on a printed lable somewhere on the vehicle, under the hood.locate the notch on the balancer or the crankshaft pulley then mark it with chalk ot a white paint marker so it will be visible under the timing light. start the engine and let it warm up to normal operating temperature then shut it off. turn off all lights and other electrical loads.With the engine off, connect the pick-up lead to the number one spark plug wire. connect the timing light power leads according to manufacturer's instructions.Start the engine and point the timing light at the timing mark by the crankshaft pulley. Take note as to where the timing notch is lining up with the timing scale.If the notch is not lining up, you have to loosen the hold down nut or bolt on the distributor. Turn the distributor until the notch lines up with the timing scale.Re-tighten the hold down nut or bolt and recheck the timing, making sure the marks didn't shift. turn of engine and disconnect the timing light.
GM has a fuse panel on the left side under the dash. The fuses are labled HTR/AC. There is also a set of overload relays under the hood on the driver's side. They are also labled. The owner's manual has a diagram showing both the location and type of fuse to use. Cleaning the sockets with electrical cleaner when you replace the fuses helps them to make better contact.
must have timing lite. Hook timing lite up to battery place spk lead to #1 cylinder remove cover from data link connector (rectangler box on fender well) lid of box has diagram of pins short pin TE1 to E1 loosen distributer and set timing to spec. Spec should be on emission lable under hood.
Should be under the hood,on a lable! You may nave to bypass the computer,and i,m not sure how so the specs alone are ok to know,but the bypass to check or set the ignition timing is a must! It may tell under the hood on a lable some where check really good!
Note: The Timing Connector breaks out of the engine wiring harness conduit adjacent to the distributer. It is a single wire sealed connector that has a tan with black stripe lead. Note: Timing specifications are listed on the Vehicle Emissions Control Information label under the hood. Always follow the Vehicle Emissions Control Information label procedures first before using the following procedure.
PROCEDURE: Set timing under the following conditions:
Normal operating temperature.
Air cleaner installed.
Transmission in neutral.
Disconnect SET TIMING connector (tan/black wire) located in the harness close to the distributor. DO NOT disconnect the 4 wire connector at the distributor.
Connect timing light and adjust as necessary by loosening hold down bolt and rotating distributor.
Base Timing, with Manual and Automatic Transmissions: 00(TDC)
Tighten hold down and recheck the timing.
Stop the engine and connect SET TIMING connector.
Clear ECM trouble code by disconnecting ECM power source.
