Toyota tune-up problems - please help!?
I'm doing a simple tune-up on a 1985 4wd Toyota pickup (4cyl 22R) and bought replacement spark plugs under the assumption that it uses a carbeurator (though apparently Toyota introduced fuel-injection models at about the same time) - once I returned home I became suspicious that it was in fact actually a fuel-injected model - as I am a novice mechanic would someone please tell me what to look for to be sure (the truck starts without pumping first, that's what made me wonder if it was actually fuel-injection), and whether or not it will make a difference if I use the spark plugs I was given at the auto parts store under the assumption that it was for a model using a carb? (I tried it anyway since by the time I thought it through I had already replaced all 4, and the truck started up just fine, but obviously I don't want to risk any future problems.)
