Hi, could use some opinions on which sensors to check first.

My car is a escort estate 1.8si R reg

car suffers from, high fuel consumption
revs sticking at around 2000 when driving
temp guage reading varying from nothing to the middle and anywhere inbetween


On previous messages it had been said that certain sensors may just be in need of cleaning, my question is in which order should i clean the following

Air temp sensor
Mass air flow sensor
Coolant temp sensor

Are Air temp sensors and mass air flow temp sensors the same thing ??

And finally, is there any other sensors that may not have been mentioned yet ??

I know thats a lot of questiuons to ask, but hey , thats what you guys are good at right ??

Many thanks.

Have something to contribute?

remove throttle body/idle speed control valve unit and clean as mentioned b4 in other post that should sort rpm problem
replace temp probe for guage "it sounds faulty" to me.
Replace air filter "high fuel consumption" or lay off the loud pedal.

I think i will give the throttle body a try and also the ISCV, i will remove the temp proble and test it.

air filter has already been replaced along with the fuel filter, spark plugs, oil filter etc.

Thanks for the info J.
