Ford has issued a TSB (TSB 09-2-6) for owners of 2005-06 Ford Escapes and Mercury Mariners with the 3.0-liter engine may find a Check Engine light with the P0351 P0352 P0353 P0354 P0355 P0356 trouble codes. Ford has discovered problems with factory installed spark plugs that have poor insulating properties. These plugs can allow radio frequency (RF) interference that can damage ignition coils and even modules. If you see just one of the above trouble codes, immediately remove the spark plug for that cylinder and look for a two-digit alpha-numeric code on the plug’s porcelain insulator. If the code isn’t shown, replace the plug with a revised plug (AGSF-32W-M1). Then clear the trouble code and replace the coil-on-plug ignition coil.
However, if you’re getting multiple trouble codes, start again by checking for the date code on the plug. If it’s not there, replace all the plugs. Then clear the trouble codes and drive the vehicle. If you get multiple trouble codes again, you may have to replace the ignition module.
