I pulled the heads off and sure enough I had a cracked piston!!! FML Dropped the oil pan and pulled the piston and have a spare long block so I took a piston from that motor and installed the used piston and put it ALL back together!!! never done anything this serious on a car before!! took almost 40hrs of non-stop work on the car to wrap it all up... started right up and had to turn it right off!! serious exhaust leak, fixed the exhaust leak and the car sounded 10x worse the before i tore it apart... after doing a ton of research i thought it was a rod bearing... dropped the oil pan and turned the motor by hand until i heard the sound it was making!!!!!! FLEX PLATE WAS CRACKED!!!!! nightmare.. pulled the motor and changed the flex plate and put the motor back and she started right up, exhaust leak again, fix that check engine light on... pulled the engine harness out and patched and repaired all the crappy wires, no more check engine light.. YAY now the car has a pretty decent vibration when accelerating or when holding the brake and the car in drive with the RPMs at 1500 it is very noticeable shakes the mirrors and such!!! and when i first accelerate it kinda feels like something is sticking like a brake then it goes away and i get a vibration only when i accelerate slowly, but nothing when i accelerate fast!!! I know i prob. put too much info but any help would be great!!!
But i must say doing all this work was SOOO much fun to me!!! it just felt great to be able to tear apart a motor and bring it back to life!! just hope i can find the cause of the vibration!! thanks again
