New T/belt - now runs crappy
Got the new belt on, fired it up and....ragged idle (not missfire), boggs down on accell., no power, loud exhust noise on accell.....timing off?
So I pulled the insp. plugs off the timing cover.....brought the crank around to TDC on Comp. stroke...looked in the holes (with a mirror)...and the stamped notches on the backing plates of the cam srocket and oil pump sprockets are both lined up with the triangles on the rear of the timing cover....so I'm good, right?
When I started doing this job, did a search and found a lot of talk about "diamonds, triangles & squares" on the cam/aux. shaft pullys. I examined the front face of each pully very closely and could not find ANY mark, faint or otherwise - only the one as noted above. Now my truck is in fact a Mazda B2500 (1999), but have been told that the engines are indentical with some very minor diff.
Truck ran fine prior to the timing belt failure...could be something else but I'm not a big believer " coincedence failures"... I did however check operation the MAF & sensor, IAC valve and EGR valve - all appear to be OK. Plugs are about 5K old... has anyone else had this happen to them?
