Over the past few weeks I've noticed that my car ('91 fox) doesn't pull nearly as strong as it does after starting it for the first time of the day. If I start it in the morning and go for a drive after its warmed up it goes like stink, but later on after driving around for a while or after starting and stopping it a few times it feels like its lost some power.
About a month ago I did a head/intake swap and when the car is cold it runs like it should with these upgrades, but when its warm it still runs good, but it feels like it did before the swap.
Any idea as to what could be causing this?
