My car is a Flex Fuel and runs smooth only when using E85 gasoline. Older models had a Flex Fuel Sensor, I understand this does not. If I use regular 10% Ethanol gas it runs rough at 30/35 in town. I have had several older Flex Fuel Crown Victoria's that had no problem with regular gas. Any Ideas if I can use regular?

Try cleaning throttle plate on both sides and iac hole with choke cleaner if that does not work scan for codes. There should not be any problem switch ig between the two.

Hi Fred54456,

Here is a link to an article that features written step by step instructions and pictures explaining how to do the scan yourself, also I have included a link to our YouTube channel with a how to video on code scanning. Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com. Once you have the codes please get back to us so that we can further assist you. We are always happy to help.
