UPDATE: took off timing cover today and rechecked all the timing marks and i found out that my intake cam gear is off by 1 tooth!

Whats the easiest and fastest way to fix this??

you most probably need to do it all over again cause timing you really wont that to be as precise as it can be! but really there is no quick or slow way to do it as long as you didnt pull the allen key out the tensioner you should be find but its still gonna be a hell taking it off, I would try taking off the idler pulley and it will have enough slack to come right off!
 
Yes, you need to take it all back apart and redo it.

There is no ifs, ands, or buts about it. There was a big arguement a while back where someone said you could just use a big screwdriver and stretch the belt up and move the cam or something crazy like that. DONT BE THAT GUY.

Just think of this as DSM Practice.
 
UPDATE: I finished redoing my timing belt and put in a new knock sensor! took it for a test drive and the car idle way better and drives alot nicer but my datalogger is still showing im getting pretty weird knock!! sometimes i will get only around 2 to 0 counts and other times i will get up to around 20 counts for some reason!???

IF the knock sensor isn't torqued right will it cause this???
 
I would suppose the answer to your question is yes - but BTW did you check Base Timing? Pretty much a prerequiste to properly grasp knock numbers after a Timing Belt install.

IMO due to the weird ass angle we have to view the Marks from when you are squatting down & peeking thru the belts & "see" 5 BTDC you are really set at about 7 BTDC - SO when you see 2.5 BTDC it's actually about 5 IMO - I try to be in the same position/angle whenever I set mine halfway between 5 & 0 BTDC & IMO that is 5 in the real world & "seeing" 0 would be 2.5 BTDC real world IMO... BTW on my Pocketlooger I'm pulling 22 - 25 advance at WOT (Tuning guide reccommends NO LESS than 15 at WOT) & see as much as 46 degrees advance on Pocketlogger in some throttle positions - ZERO knock on 92 or 93 Octane in Winter (which of course means I could bump up Timing OR Boost) - but it runs great & I don't want to fry this old Turbo quite yet - seeing 13 PSI on POS Stock gauge.

1g Idle & Timing Adjustment STRAIGHT FROM DSM MANUAL...

- Reset ECU 15 Minutes to clear all the crap out.

- With car off
- Ground that pin on the Diagnostic Connector
- Fully warm car up, No accessories on.
- Run at 2500 rpm more than 5 seconds
- Let idle for 2 minutes
- Adjust BISS 700-750 rpm
- Cut car off
-Disconnect Jumper at Diag Conn

- With Car OFF
- Connect Timing Jumper
- Fully warm up car - No accessories
- Check CURB IDLE is at 750 + or - 100 rpm (may take a little while to settle down being you just reset BISS)
- Set Timing at 5BTDC (which means you'd see 4 IMO due to bad angle)
- Cut Car OFF
- Disconnect Timing Jumper
- Cut car ON
- Check Basic Engine Timing 8BTDC (kinda jumps from 7-9 usually).

- AFTER setting Base Timing correctly per the above you could then "bump up" Base Idle a little (50 - 100 rpm) to help with the Fan cut-on - The ECU can pull more than you can retard! - Some of us have BOTH Fans cutting on simultaneously so that is loading your Alt more than a stock setup - Typically you can retard one degree when setting Base Timing & it idles smoother as long as Idle is close to spec - Setting it where you see 4 will make it more resistant to losing RPM when fans cut on.

now get to work & report back...
 
Did you torq the knock sensor to the correct spec? I don't have my manual near by but I think it's like 11-14 ft lb. But do NOT quote me on that!

Over doing it will cause phantom knock. Supposedly so will bad engine brackets. Mine are not in to good of shape at all but I dont get much knock count & my setup is still untuned so I would take that rumor with a pinch of salt.
