Hi i was an idiot and took off my hood off my 89 tbi camaro and a week later it rained when i was busy indoors. i was worried it wouldnt start but it did and i kept my hood off . weeks later after a drought in summer it suddenly rained again , iwasnt worried and when i went to start my car later it had trouble starting. it starts everytime just has trouble starting up and i 've noticed a loss in power cuz my friends mustang keeps up with me now not like before when i would always waste him.

Anyways i dont know where to start ...starter,? spark plugs? distributor?
i really would like to thank u in advance and if u have any of the parts i need lying around i would like to take them off ur hands for a decent price.
