did that already too like 6-8 months ago here is a list of stuff replaced

isolater bolts and gaskets ,cats , have new spark plug wire and spark plugs butmight need change have but about 20,000 or more on spark plugs. pcv tube and o rings on the valve covers.


only things i havent changed are 02 sensors since i purchased and blew my cats like 6-8 months ago before changed and fixed the isolater bolts and gaskets. and recently i had a leak in the ac vac line but fixed and replaced that unless it has a another hole but my ac is working when there was ahole in the ac line no ac.

 

1998 f150 300,000 starts great untill somthing opens up (sounds like themstat in water pump type click) and runs great untill you will get to red light and if its short no problem what so ever but if its a long light engine sputers like outa gas and shuts off.Restarts without a problem. If put in N it runs fine and then shift into D and goes runs fine. Just got this truck and workin out the kinks as everything else seems great. Looking for vacum leaks but no luck so far. Anyone have ideas for this one as well. Thanks

 

Just replaced egr and cleaned all sensors in the air intake with elctrical cleaner and cleaned the intake tube itself with soap and water (ruber part) while there cleaned the conctions with elctrical cleaner ,blew out air filter and all has smothed out and runs great with ac on but still gets realy bummpy without ac on at long stop. Good thing it june in Fla.
Open for ideas on how to get it right.
I owe, I owe off to work i go for another week.

 

Clear your codes and see if any of them come back.
