Experiencing a shaking issue in your 1996 Lincoln Town Car accompanied by an OBD2 sensor error can be concerning. This often indicates that your engine is misfiring, meaning some cylinders are not firing correctly. Let’s explore potential causes, focusing on how to address this issue effectively.
One common culprit behind engine misfires and OBD2 errors in 1996 Lincoln Town Cars is related to the spark plugs and ignition system. Older Town Cars, like your ’96 model, might still have the original spark plugs, or replacements that are not ideally suited for the vehicle. Ford originally equipped these cars with AWSF 32 P and AWSF 32PG spark plugs, which were half-thread designs. Due to issues, Ford later recommended AWSF 32PP as a replacement and shifted to full-thread AGSF plugs. The type of spark plug used is indeed important for optimal engine performance.
If you’re facing a “96 Lincoln Town Car Obd2 Sensor Says Error” message and engine shaking, inspecting and potentially replacing your spark plugs is a crucial first step. Consider using high-quality replacements. NGK G-Power spark plugs are a viable option, offering good performance. For your 1996 Town Car, compatible spark plug options include copper-based NGK plugs with a V-cut center electrode, G-Power fine wire center electrode plugs, and double platinum plugs which are comparable to Ford’s recommended plugs. Motorcraft also lists SP-493 fine wire platinum plugs and SP-413 nickel alloy plugs as suitable.
When replacing spark plugs, ensure you apply the correct torque. While the specification is 7 to 15 lbs ft, some find that snugging them up to around 20 to 25 lbs ft provides a better seal.
By addressing the spark plugs, you can often resolve misfire issues and clear the OBD2 sensor error in your 1996 Lincoln Town Car. If the problem persists after spark plug replacement, further diagnostics of the ignition coils and related systems may be necessary.
