K guys so its been months now and my celica is still down on power. I've had other people who have had 6th gen st's drive it and they say the same. Like I stated earlier in the thread my friend advanced the timing almost all the way to get the thing operating normal or at least semi-normal. However there is still a noticeable power loss and I'm having trouble diagnosing it. I'm over at my friends house and we are going to vacuum test it tomorrow as well as retard the timing back to factory to try and trace the problem. If you guys have any suggestions as to what else might cause the power loss it would be greatly appreciated.
The following have been ruled out: spark plugs(replaced) spark plug wires(replaced) fuel filter(replaced) injectors(do not contain water) No check engine light or other idiot lights so NO code to diagnose Distributor has no water and appears to be working fine Thanks again guys -------------------- |

QUOTE (stephen_lee @ Oct 2, 2011 - 1:50 PM)  turn engine till notch on crank pulley lines up wit the 0* mark on the timin cover. pull valve cover off. hole in timing gear should match with notch in camshaft cap behind it So we did this today and the timing is correct, tdc is correct etc. Also we did a compression check and results were as follows: Compression on #1 Cylinder = 200 Compression on #2 Cylinder = 190 Compression on #3 Cylinder = 200 Compression on #4 Cylinder = 190 To add when I was underneath the car turning the motor over by hand, I could hear what appeared to be pressure or air escaping. I'm not sure if this is normal but it sounded like it was coming from inside the cylinders so that's why we did the compression check. I'm probably going to buy a vacuum gauge this weekend and check that as well. Any other ideas guys? It is much appreciated  -------------------- |
