odd idle and problem with the pistons
hey.
here in LA, the weather is hot. i was washing the car today and after i wanted to start it up but it had a bit of difficulty. i've noticed this before in the other cars when trying to start them on a hot day when they haven't been used for a day or so. the car smoked from the exaust for a moment after it started but it idled at about 500 rpm. i turned it off and started back up and then it idled at about 800 rpm without any smoke. however, the car was vibrating a bit. i opened up the hood and noticed something odd in the engine. on a gen 3.5 5S-FE, on top of the engine are 4 cabled that i am assuming to be spark-plug cables that go into the cylinders. the #2 and #3 cylinder cables were shaking. i put my finger on them and felt the piston hitting hard. it was noticable in the 1st or last cylinder. only in 2 and 3 i could actually feel the piston hitting hard. i went to the other toyotas we own. we have a 3S-FE and a 7A-FE. turning them on, the 3S-FE smoked as usual ( need to clean injectors) and the 7A-FE went fine. opening the hood and trying the cables over the cylinders, i did not feel the pistons hitting at all. so i went back to the camry and tried it out again and the 2nd and 3rd piston were hitting pretty hard. any suggestions?
sorry for this long thred but i am beggining to be a bit worried from it. i had this car for almost 2 months and the vibrations at idle were always there but today i also noticed the pistons....so yea.
All if any suggestions are highly appreciated. thanks!
