well we had to do the timing belt , then couldn't get it to run , found out the fuel pump was bad , so i changed that , then it would not run worth a crap and the guy that i got it from changed the throttle body so we found the mass air flow was bad , went to the pic and pull got the only one they had it ran a little better so i got it to a friends house and we sprayed brake cleaner around the bottom of the tbi had vac leak pulled the tbi off he ddidn't put a gasket under it at all got me a cracker box made gaskets put back together runs fine and then fixed a couple exhaust problems it still has a lifter tap but i can live with that ..
