Is my computer dying????
Here's the story....
Bronco runs fine then starts pinging under heavy load about 2 weeks ago. Now it will hesitate bad from a complete stop unless I ease into it. This happens after it warms up. Checked timing and it was 20 BTDC w/o the spout and I noticed that the dizzy bolt was loose. Set timing to 10 BTDC reconnected spout, computer adjusted timing to about 13 BTDC. I seem to remember when I put in a new dizzy the computer took it way over 20 after the spout was connected. Still hesitates as before BUT if I keep the spout out it runs like a champ no hesitation no ping, hell it runs better then ever.
Details....
New in the last 6 months or so.
EGR valve and position sensor
O2 sensor
Dizzy and ICM
Idle air control
MAP and TPI both test good and there are no codes.
Is my EEC going out so that it is having trouble setting the correct timing or heaven forbid the dreaded timing chain????
Also can I run it without the spout connected?? Is this an option if say I have to replace the timing chain and cannot get to it for a couple of months?
Thanks in advance
