I did a dry test on the engine my results were going from right to left side of engine 160 60 and 30 . Anyone point me in the direction to a thread that would explain what can be wrong? pistons or piston rings? Also my corroborator seems to be having tom much fuel in there.. anyone might know whats wrong i don't think its fuel pump. |

Your fuel injectors probably bad, your valves are burnt, rebuild engine, test all the sensors, and test your fuel injector.... I can help if you want to drive 5 hours to see me :-) |

It's simply worn out. Doesn't matter what is wrong, makes no sense to take it apart without doing it all. |

if you can find a motor with good compression then change motors. Be sure and check the compression BEFORE buying the motor, no matter how good the salesman says it is, even if it is garrenteed. |

150+ is good 180+ is great all cylinders readings should be within 10% of each other |

If his intake manifold is on, won't he have to have a wide open throttle as well to insure adequate air flow? |
