Ok, heres the lead-up
Its a 91 4.0 I6 .... its been sitting about 6 months because of a bad CPS and an owner too lazy to get under it (me).
I changed the CPS ...... ran, but really poorly, discovered a spider in the distributor. .... and a code for a bad pickup..... pulled the distributor,changed it out and now have what I thought were problems with timing.( hard start, breaks up on hard throttle, loss of power)
I thought i was a tooth off . I tried moving +/- 1 tooth, still was weird, i snapped off the tabs and tried rotating the distributor.
If I retard it I get a smooth start but breaks up badly on accel.
If I advance, barely starts and only runs marginally better.
Now my question. I'm now getting a code 13 for bad MAP sensor. Before I change it out (I hate to diagnose by dumping money) .........
Do you think the MAP is bad or would the other situation cause it to show bad on the computer. It just seems a little strange that they would all go bad in rapid succession. (I'm starting to think the local parts store has a remote control for my check engine light. They just press it on slow days to drum up business.
thanks
