I was changing timing belt/tensioner/bearing/water pump on a 1996 sc400. I aligned all the marks and made sure everything was in place. Started the car up, ran fine for 2 min. I decided to go around for a spin, as soon as I start leaving the drive way the car starts stuttering and driving like poo and check engine light came on. Now.... is this a symptom of setting the timing wrong? dist. rotors are not aligned right? I need to know ASAP.

Never will I perform a DIY timing belt on anything more than 4cyl.

Check the codes-- You may just find your problem by disconnecting one or the other coil wires from either/or distributor--- If I'm right, one will cause no change in the poor running, indicating a problem with ignition on that side, then work your way back from there-- could be a cam sensor with a bad connection, a coil that decided to go bad precisely when you decided to change the belt, or other things I can't think of right now, but you get the idea......

I rented a scanner from autozone, it is saying cam shaft position sensor bank1. Which sensor is this left or right?

hmmm-- that I don't know-- BUT-- planetsoarer and lextreme both have very good tech articles that will probably answer your question--

Here's a blowup of all the components:

Bank1 is the left side(diver side).

Lexus dealer, bought 2 of the cam sensor cost me a little over $300. You would think this would fix the problem no! im going crazy here. Check engine is still on spitting the same code, and sputtering. I disconnection the bank 1 cam sensor, and it runs fine! with the exception of the check engine light. Can someone please help, im digging into deep money here. id like to get this over with! thanks!

why would you buy cam sensors when the code says "crank sensor" ???????

Secondly, you may be able to get a good crank sensor from aliga for a seriously good price-- he's the man-- really- he's the man--

Sorry it was a CAM SHAFT SENSOR!

Now i talked to a few people they are telling me that the cam sensor could be set of due to timing being off, teeth not being placed right.

is it possible to adjust the timing with just the rotors off?

I mean not taking it all down again....
