Look under the dash for a single wire connector right side under the glove box.
what year? popping like a backfire through the intake? check the timing if it has a distributor.
It should be 6 degrees before tdc, just make sure you disconnect the distributor's computer control wiring harness before you adjust, and check the timing with a timing gun.
To set the timing on a 1994 Chevy Blazer 1500 5.7L 4x4, first, ensure the engine is at operating temperature and then turn off the engine. Disconnect the timing connector (usually a single-wire connector near the distributor) to disable the computer's control over timing. Use a timing light to check the timing mark on the harmonic balancer, adjusting the distributor as needed to align it with the specified timing mark, which is typically 0 degrees BTDC for this engine. Finally, reconnect the timing connector and re-check the timing if necessary.
0 deg -or- TDC With the distributor timing connector disconnected.
Start with your basic tune up procedures. Check your spark plugs, wires, distributor cap and rotor. Check compression, all cylinders should be within 15 lbs of each other. Check carb adjustments. Check for vacuum leaks. Check timing. Check fuel and air filters.
To set the timing on a 1997 Oldsmobile Achieva, first ensure the engine is at operating temperature and then disconnect the timing connector, usually located near the distributor. Next, use a timing light to check the current timing mark against the specified timing in the service manual. Adjust the timing by loosening the distributor hold-down bolt and rotating the distributor until the correct timing is achieved, then retighten the bolt and reconnect the timing connector. Always double-check the timing after adjustments to ensure accuracy.
remove distributor and check the gear on it.if gear is ok then remove front cover and check timing chain or broke camshaft.
Loosen the Distributor hold down bolt enough that the distributor can be moved by hand. Locate the timing bypass connector that is sort of hanging out of the electrical harness at the right (passenger) side front strut (shock) tower. it is connected to a TAN wire with a BLACK stripe. Use a jumper wire and make a good connection with the connector's metal tab and ground the other end of the jumper to a reliable ground. Connect an INDUCTION timing light and to #1 cylinder spark plug wire near the distributor. Start the engine and move the distributor to align the crankshaft TDC mark with the 10 degree mark on the timing pointer. Stop the engine and remove jumper and timing light. Tighten Distributor hold down bolt. Start the engine and test drive. NOTE: Grounding the bypass wire to set the timing may cause a code 42 to be logged in the ECM. Disconnect the battery for a few minutes to clear the code.
To set the timing on a 1991 Mazda MX-6, first, ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Remove the distributor cap and align the rotor with the timing mark on the distributor housing. Use a timing light to check the timing mark on the harmonic balancer against the timing scale on the engine; adjust the distributor as needed to achieve the correct timing specification. Finally, recheck the timing after tightening the distributor hold-down bolt.
see if you are getting spark in your wires. or check for cracks and damage.

To fix the timing on your 1993 Buick Roadmaster, first, ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Then, check the timing marks on the harmonic balancer and the timing cover to determine if adjustments are necessary. Use a timing light to check the current timing and adjust it by loosening the distributor hold-down bolt and rotating the distributor until the timing light indicates the desired setting. Finally, retighten the distributor bolt and recheck the timing to ensure it's correct.
