Car was running fine had fuel line leak so I replaced sender now car wont stay running I cleaned egr and multi port everything was filled with carbon removed all of it car will idle fine if cold it runs great once warm bogs wont climb. straight aways it isnt bad. can get it to 50 but I live in the hills of pa. I have replaced cap &rotor they were BLACK and heavily pitted. Could timing belt be going? it does start and Idle press gas and it will die feather the gas and it builds. cant just step on it

Check the fuel pressure when the problem exists.
