Hard to push gas pedal

Hey on my 92, its hard to push down the gas pedal, any known reasons for this?? i lubed all the points goin in and out the firewall thinking that was it, but no such luck, is somehting wrong with my TBI?

Has it always been stiff?

I know my '90 has a real stiff cable compared to my Dads 94 (personally; I like it.) but I located it to being caused by my tanys TV Cable. Just a very stiff spring. It seemed normal to me (this is my second '90; same pedal)

yea [I]for me its always been like this, but i drove my buddies 93 and it was extremely easy to push, but i thought the same about mine thinking it was normal, but even my mechanic who works on these trucks religously noticed it and said it was hard to push

Have you cleaned the throttle body bores recently? When you do, you might also want to clean up the IAC air passages.
