PGG 0 Posted January 13, 2019 Report Share Posted January 13, 2019 This is my first time posting on this site, and I need some expert advice please. My Taurus SE is a 2006 model with 25k actual miles. I haven't had any trouble with it until now. I took it on a 200 mile round trip last week & everything was fine. When I next started to take a ride, I noticed that the engine misses at higher rpm. I discovered it like this. I got out to close my gate & thought I heard a little squeaking from under the hood. I reached in and revved the engine and it starts missing above 3200 rpm. There is no check engine light on. When I attached a code reader it does not indicate a problem. Anybody got any ideas?

wendorms 0 Posted January 13, 2019 Report Share Posted January 13, 2019 Your belt might be slipping at high rpm causing your alternator to send insufficient voltage to your ignition system. Quote Link to post Share on other sites
PGG 0 Posted January 13, 2019 Author Report Share Posted January 13, 2019 Thanks. I'll check it. Quote Link to post Share on other sites
PGG 0 Posted January 13, 2019 Author Report Share Posted January 13, 2019 OK. I installed a new belt and it seems to have helped a lot. When I rev the engine it doesn't miss until about 4500 rpm. When driving, I can't detect any missing at all. I never would have figured that belt to be causing the problem. It looks great. I clearly have a lot to learn about the Taurus.....Thanks for the help! Quote Link to post Share on other sites
wendorms 0 Posted January 13, 2019 Report Share Posted January 13, 2019 Glad to help a fellow Taurus owner, mine is a 2004 SE and runs like a boss. Have you ever checked the OHMs of your spark plug wires? You might have one or more that are failing at 4500+ rpm. Those OEM coil packs can cause misfires too. Quote Link to post Share on other sites
Bull Geek 812 Posted January 14, 2019 Report Share Posted January 14, 2019 If squeak is coming from the driver side of the motor suspect the camshaft synchronizer. Buy a ford one if you need it - Dorman is utter garbage. squeak passenger side - could be a pulley. be sure to do a good flush on your cooling system if it hasn’t been done in last 5 years.

PGG 0 Posted January 14, 2019 Author Report Share Posted January 14, 2019 Thanks! I will check it out. Quote Link to post Share on other sites
wendorms 0 Posted January 14, 2019 Report Share Posted January 14, 2019 I wouldn’t worry about your cam synchronizer with only 25K miles, since they’re good for 75-80K miles when it’s smart to replace the rotor in the top part of it. Quote Link to post Share on other sites

PGG 0 Posted January 14, 2019 Author Report Share Posted January 14, 2019 Lol...Age has certainly taken a toll on ME! Can you guys recommend a good book on Taurus troubleshooting / repair? Quote Link to post Share on other sites

Knew a car that had it failing at 49k...so yes you should worry about it book...ford factory manual from eBay! Quote Link to post Share on other sites
