i've don alot of engine work recently and i just got everything put back together and took er for a test drive. major power loss under load. idles and revs fine but it wants to stall out when i let out the clutch and it has a "can of spoons" type rattle under load.
i checked the timing with a light and it reads 20* advanced off cyl 1. if i turn the dist. wont that throw off the even side (2,4,6) ? is it possible that the timing belt is off a tooth or two on the odd side (1,3,5) and could advance my timing 10*?
heres a list of my recent engine work:
-plenum cleaned out
-intake cleaned
-injectors sonic cleaned and serviced
-new top end gaskets
-new wires, dist. cap and rotor. (plugs 3 months old)
-new fuel filter
-new o2 sensor
-new air filter
-*erg coming off as soon as i figure out the timing.

problem solved!!!!
so the cam timing was way the heck out. the left was 6 teeth counter clockwise and the right was 1 tooth ahead clockwise. all in all not too hard to fix. i didnt have the hydro tensioner either. i also disconnected the egr. seems to have yielded some gains in throttle response.
all in all with the work that i did my truck sure seems a lot more peppy!
thanks everyone!

Don't forget to stick a 1k ohm resistor in that EGR temp sensor so it doens't throw a code at you.

ok, so on top of all the bad luck i am having recently. it seems my timing is yet again off (by only a small amount this time) my truck is stuttering like it did before with some minor power loss.
it has only been maybe 1000km since i adjusted it last. is there a reason that i am missing for the timing to slip like this? my belt is as tight as it can get with the tensioners. why would it go out like this? again?
