Question about 1994 Pontiac Sunbird
It has new plugs,wires,temp control sending unit,fuel pump,fuel filter,and o2 censor. if you ease into the throtle you can rev it up to red line no problem. If you floor it, it will bog down the same thing happens when you drive it . from stop if you ease into it and slowly as you gain speed give it more gas it's ok but if you give it to much it bogs down and you have to take your foot off the gas and ease back into it. At higher speed like 65-70 you can floor it and it will drive fine. Oh yeah it does not like hills same thing happens as before but worse and the same when there a few people in the car
Check mass air flow sensor. Also check cap and rotor for "tracking". Check coil. Have someone check codes...most "supermarket" type parts houses do this free! fouled injectors may cause similar problems but keep this in the back of your head for now.

It sounds exactly like the problem i had with my 93 pontiac sunbird adn it turned out the valves in cylinder #1 had burnt them selves out over age so i suggest you take it to your local college and get them to take it apart for dirt cheap and fix it for a couple of reasons. 1.Saves you the money. 2.Gives them a learning experiance. 3.They usually will guarantee your problem is now fixed.
