If you have a 5.7 Tbi, you may be wondering how to set the timing. Timing is an important part of getting your engine to run correctly, and it’s not always easy to do. Here are a few tips on how to set timing on a 5.7 Tbi:
First, make sure that all of the spark plugs are in good condition and firing correctly. Next, check the distributor cap and rotor for any damage or wear. If everything looks good, it’s time to start setting the timing.
To do this, you’ll need a timing light and a friend to help you out. Have your friend hold the light while you rev the engine up to about 2,500 RPM. At this point, you should see the timing mark on the pulley align with the mark on the block.
If it doesn’t line up perfectly, don’t worry – just make sure that it’s close.
Once you’ve got the timing set, it’s time to adjust the idle speed screw until the engine is running smoothly at idle. That’s all there is to it!
- Remove the distributor cap and rotor
- Locate the #1 spark plug on the engine
- This will be the spark plug closest to the front of the engine on the driver’s side
- Insert a piece of wire or a small screwdriver into the hole in the center of the #1 spark plug
- Turn the engine over slowly until you feel pressure build up in the hole in the spark plug
- This is when you are at Top Dead Center (TDC)
- If you are using a timing light, hook it up to the battery and point it at eitherthe harmonic balancer orthe timing marks onthe pulley behindthe harmonic balancer while a helper cranks overthe engine slowly withthe ignition keyuntil yourtiming lightstarts flashing

350 Tbi Timing at Idle
If your 350 TBI is idling too high, it could be because the timing is off. You can adjust the timing by loosening the distributor cap and turning the distributor. If you turn it clockwise, the timing will advance; if you turn it counterclockwise, it will retard.
Once you’ve made your adjustment, retighten the distributor cap and start the engine to see if the idle has changed.
How Do You Set the Timing on a Tbi Engine?
If you have a TBI engine, the best way to set the timing is to follow these steps. First, find the Top Dead Center (TDC) mark on the flywheel and make sure the piston is at TDC. Then, loosen the distributor hold-down clamp and rotate the distributor until the rotor is pointing to the number one cylinder on the firing order.
Once you’ve done that, tighten down the distributor clamp and recheck your work. Finally, connect a timing light to the number one spark plug wire and check that the timing mark on the harmonic balancer lines up with 0 degrees on the timing scale.
How Do You Set the Timing on a 1989 Chevy Tbi 350?
In order to set the timing on a 1989 Chevy TBI 350, you will need to connect a timing light to the number one spark plug wire. Once the timing light is connected, start the engine and let it idle. With the engine idling, point the timing light at the harmonic balancer and observe the mark on the balancer.
The mark on the balancer should line up with the zero mark on the timing tab when viewed from above. If it does not, loosen the distributor hold-down clamp and rotate the distributor until the marks line up. Once they are lined up, tighten down the distributor clamp and recheck your work with the timing light.
How Do You Set the Timing on a 1987 Chevy 305 V8 Tbi?
If you have a 1987 Chevy 305 v8 TBI, setting the timing can be a bit tricky. Here are a few tips to help you get it done:
1. First, find the Top Dead Center (TDC) mark on the harmonic balancer.
This is usually located at the 6 o’clock position.
2. Next, locate the timing marks on the crankshaft pulley. There should be two lines or hash marks; one should be at the 12 o’clock position, and the other should be at the 6 o’clock position.
3. Match up the TDC mark on the harmonic balancer with the 12 o’clock position on the crankshaft pulley. This will ensure that your engine is in its correct firing order.
4. Once you’ve matched up these marks, use a timing light to check that your distributor is pointing to where number one cylinder should be firing at TDC (top dead center).
If it’s not pointing to this spot, you’ll need to adjust it accordingly. To do this, loosen The hold-down clamp bolt and turn The distributor until The pointer is In line with The TDC mark..
After making your adjustment, retighten The hold-down clamp bolt securely.. If everything looks good so far, go ahead and start your engine and let it idle for a few minutes.
. 5Now it’s time to set your ignition timing..
With your engine still idling,. disconnectThe vacuum advance hose from The distributor.. Then using a timing light,. shineThe light ontoThe crankshaft pulley while someone else watches The dial onThe dashboard.. AdvanceOr retardThe distributorUntilThe dial reads 8 BTDC (Before Top Dead Center) At 1k RPMs AndReconnectThe vacuum advance Hose when finished… NowYour1987 Chevy 305 V8 TBIIs Properly Timed!
How Do You Set the Timing on a 1994 Chevy Truck?
The timing on a 1994 Chevy truck can be set by Adjusting the distributor. To do this, first locate the distributor cap and rotate it until you find the number one cylinder. Once you have found the number one cylinder, remove the distributor cap and look at the rotor.
The rotor should be pointing to the number one spark plug wire on the distributor cap. If it is not, then loosen the hold down clamp and rotate the distributor until the rotor is pointing to that spark plug wire. Once you have done that, tighten down the hold down clamp and put the distributor cap back on.
