I am having some promblems with my 1993 ford f-150
it seems i am losing power.I mean i can get up to 55-65 with no promblem but if i go to pass someone it seems to lay back.I passes them but just doesn't have the power do do it quickly.The truck never had promblems passing ever.

I put in spark plugs in about a two years ago the 100,000 thousnd mile plugs.New spark wires at the time.
Just put in cap and rotor.a new feul filter about a year ago.The truck has about 140,000 on it.Not to bad for a windsor motor.is there anything else i should look into or any thing else it could be.It has tons a power starting up

sounds like a failing or weak fuel pump to me. do a presure check on fuel system.


i just reread your post. i would check the plugs and fuel filter for sure.

refer to your owners manual for routine maintainance and dont trust. getting 100,000 out of a set of plugs.

Ok thanks again bud
I thought 100,000 sounded to good to be true also but it was my brother truck at the time he wanted them.

Also what is a better plug for that truck it has a 351 windsor in it.He put in bosch last time or maybe it was splitfire i can't rember.

Thank for taking time to awnser my questions.I'll check those things out
