i have a 1995 vx LC 1hd-ft ... all of a sudden the starting operation has changed , winds over different, like the timing had changed, use to just flick key and go, now takes about 2-3 seconds, also the rev has increased by about 250-300 and is now sitting at about 950-1000 rpm, also smells very rich, and blue/white smoke in morning until warm, i have had a couple of auto sparks check all electrical circuits , and seem ok,... can these jump in the timing?? , fuel pump timing, engine timing ..??or any other issues can cause this trouble, thanks
