PandaDog15 Posted May 30, 2016 Share Posted May 30, 2016 Hi All, I'd just like to share my experiences I had when I bought my used 2011 Fiesta 1.4 zetec 26500 miles . When I bought it I reset the trip computer. I went from London to Bath and London to Northampton so covered around 400miles. I averaged 36-40mpg. recently,as it was a used car I did some cleaning under the bonnet. I stuck a new Mann air filter in (old was a bit dirty), cleaned the MAF sensor, reset the ecu by disconnecting the battery then drove the Northampton and back, which consists of a fair bit of London city driving and motorway (170miles) I managed to achieve 49.5MPG! and I was driving it normally. If you find you have low mpg, why not give this a try :) Quote Link to comment Share on other sites More sharing options...
Bobr Posted May 30, 2016 Share Posted May 30, 2016 Thanks for the information. I had never heard of a MAF sensor before and I've just found mine and it's easy to get at. I wonder if Ford clean them during a service. Bet they don't. Quote Link to comment Share on other sites More sharing options...
iantt Posted May 30, 2016 Share Posted May 30, 2016 No cleaning normally required on 1.4 petrol, 1.4 diesel can get a bit oily after a while and some ford dealers will give it a quick squirt with cleaner. 1 Quote Link to comment Share on other sites More sharing options...
PandaDog15 Posted May 30, 2016 Author Share Posted May 30, 2016 Hey Bob, when I got my MAF out it was covered in a bit of oil and dirt. It's easy to do. I got some CRC MAF cleaning spray from eBay. Be carful not to touch the sensor inside and let it air dry 1 Quote Link to comment Share on other sites More sharing options...
Bobr Posted May 30, 2016 Share Posted May 30, 2016 Thanks Andy. I've ordered the cleaner and I've found out how to remove it. I'll be cleaning it tomorrow. I'll do the one in my wife's Focus too. Quote Link to comment Share on other sites More sharing options...
Bobr Posted May 30, 2016 Share Posted May 30, 2016 Incidentally, I got the cleaner from amazon. Quote Link to comment Share on other sites More sharing options...
Bobr Posted May 31, 2016 Share Posted May 31, 2016 Can you tell me which bit need to be cleaned please? Quote Link to comment Share on other sites More sharing options...
PandaDog15 Posted May 31, 2016 Author Share Posted May 31, 2016 Hi Bob, The sensor is the metal wire with the black resistor type thing in the middle. Give it a good blast with the cleaner and leave it to air dry for a few mins. Disconnect the battery beforehand and reconnect once everything is dry and back in. Doesn't look too dirty tbh Quote Link to comment Share on other sites More sharing options...
Bobr Posted May 31, 2016 Share Posted May 31, 2016 Thanks Andy. I thought that might be it. It does look a little brighter after a good squirt with the cleaner. Never thought to disconnect the battery but everything is still running fine. Quote Link to comment Share on other sites More sharing options...
Bobr Posted May 31, 2016 Share Posted May 31, 2016 Incidentally, my wife's 60 plate Focus Titanium doesn't seem to have one. Quote Link to comment Share on other sites More sharing options...
