Attempting to adjust the timing yourself without specialized tools and knowledge is highly discouraged. You'll likely damage the engine or the PCM.
Here's why you shouldn't try this at home and what you *should* do:
* No Adjustable Distributor: Windstars don't have a distributor with a timing adjuster. The timing is controlled electronically.
* Requires Specialized Equipment: Accurate timing adjustments require a scan tool capable of reading and potentially adjusting crankshaft and camshaft sensor signals, as well as monitoring engine parameters in real-time. A timing light won't work.
* Potential for Damage: Incorrectly altering the timing signals can lead to engine damage, including bent valves, piston damage, or even catastrophic failure.
* PCM Issues: Timing issues are often symptoms of a problem within the PCM, camshaft position sensor, crankshaft position sensor, or other related components. Addressing the underlying problem is crucial.
If you're experiencing timing-related issues (like misfires, rough running, poor performance), here's what you should do:
1. Diagnose the Problem: Take your Windstar to a qualified mechanic or use an OBD-II scanner to get diagnostic trouble codes (DTCs). These codes can pinpoint the source of the problem.
2. Professional Repair: Let a qualified mechanic handle the repair. They have the necessary tools, knowledge, and experience to diagnose and fix timing-related issues correctly. Replacing faulty sensors or repairing the PCM are often the solutions, not adjusting a "timing" setting.
In short, forget about adjusting the "engine timing" on your Windstar in the traditional sense. Focus on proper diagnosis and professional repair to address any performance problems.
