I have changes coil,plugs, maf and air filter . Starts and rans but will not get over an idle even with foot feed on the floor , what am I missing?

Is there a vacuum leak that you can hear hissing under the bonnet?
Try disconnecting the MAF sensor plug as it would default to a preset value

If none of the above and it used to run fine then go back over your work and see if there is something missed or unplugged

Ok thanks but I have twice already. I found out the throttle body motor was shot so had to replace the throttle body . Fixed the problem.
