A 2001 echo a tune up , you will need sparkplugs , air filter , pcv valve and i would put some injector cleaner in the tank to help clean the fuel system, this cars fuel filter is inside the gas tank and is good for the life of the fuel pump and doesnt need replacing at this time,. take note that alot of the newwer toyotas use iridium sparkplugs, you will see a notice under the hood on a small sticker its sometimes located on valve cover or on radiator post warning you to use iridium plugs. i hope this helps, good day.
Hi, to change spark plug first remove coil over connecting clip ensuring to depress connector release. Next remove coil over retaining bolts. Remove coil over carefully directing coil toward driver side until rubber end able to flex out of sparkplug access tube. Remove sparkplug using sparkplug socket with rubber insert. Had to remove ratchet to gain enough clearance. At this point you should be able to remove sparkplug by tilting extension & socket toward drivers side of car. Then lay horizontal & remove toward passenger side of car. If unable to gain access in this manner you probably have too long an extension. Take care as not to damage spark plug coil over as they are considerably expensive.
This vehicle's sparkplugs are located on the intake, right beside the fuel injectors. This is a time consuming job, and it is recommended to replace all COPs (Coil on plugs) very costly!! **WARNING**>> Work on the plugs with the engine cold, these engines are know for very little sparkplug threading and causing the plugs to eject while in operation. Be very carfeful installing as they are installed at an angle.
