SOURCE: my 1981 chevy El Camino V6 3.8L 229 idle gets high

Sounds like a problem with your choke. It may just need to be cleaned (linkages and all). If the choke doesn't close after reaching operating temperature, the engine will rev high. This indicates a choke stuck in the open position. Also, you may need to look for a vacuum leak if cleaning it doesn't fix it. On a 1981 GM product, I'd expect the vacuum hoses to be stiff and cracking.

SOURCE: i search the temperature sensor

The temp sensor for the gauge is in the drivers side head between the #1 and #3 spark plugs. The one for the computer (if you have a ccc carb) is in the intake by the thermostat housing.

SOURCE: No timeing marks on a chevy 383 stroker engine

you could bring it up on tdc on comp stroke and make your own mark on crank pulley and block then at least you know where tdc is and google some 383's that have close to same equip as you and see what degree they are running or just play with it and see how it runs .

How do I know which 3.8 is in my 1984 El Camio 229 or 231?


3.8L (229 CID)The 229 cid (3,751 cc) engine was first introduced for the 1980 model year and was produced until 1984. This engine replaced the 250 cid in full-size Chevrolets and Camaros as the new base V6. Additionally, the intermediate Chevrolet Malibu and Monte Carlo also used the 229 cid as a replacement for both the 200 cid V6, and the 231 cid Buick V6. Both the Buick V6 and the 229 cid Chevrolet V6 are 90-degree V6 engines, and both are often referred to as the 3.8L V6. These engines should not be confused as being the same, and are completely unique engine designs.
The 229 cid has a 3.736-inch bore and a 3.48-inch stroke, identical to the Chevrolet 305 cid V8 engine. The 229 cid used the same 2.45-inch main bearing and 2.10-inch rod bearing diameters as the 200 cid V6 engine. Also like the 200 cid V6, the 229 cid used the same crankshaft with the 18-degree offset throws and the same 5.7-inch connecting rods with 0.050-inch narrowed ends. It came equipped with 1.84-inch intake valves and 1.50-inch exhaust valves. The 229 cid V6 was only equipped with a 2-barrel carburetor. For 1980 the 229 cid used a mechanical Dualjet. From 1981 to 1984 the electronic Dualjet was used along with the GM's CCC (Computer Command Control) system. The 229 cid was rated between 110 and 115 hp (86 kW).

Timming seems to be off--its back firing


Turn the engine by hand till the timing mark on the pulley is aligned with 0 on the timing scale (right side of pulley) If the rotor is pointing at the rear of the engine, turn one more time...it is now pointing at #1.
cylinders are 1,3,5,7 on drivers side, 2,4,6,8 on passenger side (front to back) Order is 18436572.

Engine misfire


The computer will take time to learn the new pattern. The computer is what actually controls the timing and when the system has been reset, the computer has to relearn. Can take up to 20 starting times.
