I just installed a new timing belt and water pump on my 2001 toyota camry. The old belt broke. I tested it with the alternator, serpentine belt, and upper timing belt cover off. ( to make sure the belt had proper tension. It ran smoothly, but the positive wire for the alternator shorted to the exaust manifold. I shut it down and I had to replace the 100 amp alternator fuse. I put it all back together and now it runs really rough. And is hard to start. It does not idle steady. When idling it slows way down and stalls. I rechecked the timing and it is spot on. I did a compression test and it had pressures of 215 psi #1, 210 psi #2, 210 psi #3, and 210 psi #4. I am not getting g any codes, but I have not driven it since changing the timing belt. Any Ideas? I have been checking ground wires and am about to test the crank and cam sensors....
