fuel filter change?
i got a timing belt and water pump change about 3 months ago, and after that my acceleratioin just slowly decreases. its getting weaker and weaker by the week, and i wonder if its the fuel filter or something. i know i lined up everything right on the t-belt change, and i replaced spark plugs, cheaned the dizzy, have a clean air filter. so what could be causing it? a clogged fuel filter? oh yea my D15b7 has about 230k on it

Run a compression test. You might have some blow by from old rings.. If this checks out try replacing the fuel filter. It's a good idea especially with that mileage. Besides they are like $20. I would also run a tank or premium with fuel injector cleaner..

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by alotawatts »</TD></TR><TR><TD CLASS="quote">You Got a T-belt and pump change - or YOU DID the T-belt pump change ?</TD></TR></TABLE>Very good question, I also was thinking that the belt could have jump some teeth and as time goes by your valves are getting more and more fucked up. Makes complete sense though if the cylinders aren't holding compression. No compression, incomplete combustion if any at all. It is very important that when tensioning the timing belt to:
1. Loosen tensioner 180° from stock torque spec. of 33lb-ft. (Oh yeah make sure when you installed the timing belt you first put it on the timing belt drive pulley on the crank, then the adjusting pulley, then the water pump and finally the cam pulley.)
2. Rotate the crankshaft COUNTERCLOCKWISE!! 3-teeth on the camshaft pulley to create tension on the timing belt.
3. Make sure the timing belt and camshaft pulley are engaged securely.
4. Torque the adjusting bolt to 33lb-ft
5. Rotate the crankshaft 4-6 times counterclockwise to insure there is no contact between the timing belt and other components and to insure the belt positions on the gears.
6. Turn the no. 1 cyl to TDC and make sure both the cam sprocket and crank are both at TDC.
7. Put **** back together and wham, your done..
I would leak down and compression test the motor not only because of the mileage but also the symptoms you described..
