I think the dlc port isnt working
Expert:  david craig replied 5 months ago.

Hi Im David, first thing to do is check for 12 vdc at pin 16 of the dlc connector. and ground at pins 4 and 5.

Customer: replied 5 months ago.
Hi, David, I will try that and get back to you
Expert:  david craig replied 5 months ago.

ok, great

Customer: replied 5 months ago.
Pin 16 had no +12v and i routed it to the fuse panel where there was a missing fuse... popped it in and got some fault codes..
Expert:  david craig replied 5 months ago.

ok. let me have a few moment.......

Expert:  david craig replied 5 months ago.

lets take care of 151 first and replace the sensor. then we need to find out what cylinders are misfiring. does your scan tool read misfire data?

Customer: replied 5 months ago.
I just purchased the veepeak wifi reader than links to my iphone.. i dont recall if it does or not, I'll have to check again... what am i looking for?
Expert:  david craig replied 5 months ago.

misfire counts on each cylinder.

Customer: replied 5 months ago.
This is all there is
Expert:  david craig replied 5 months ago.

ok. gimme a few

Expert:  david craig replied 5 months ago.

Expert:  david craig replied 5 months ago.

I was spraying carb cleaner in the engine bay and noticed the distributor cap had a bit if movement (shifting side to side) could that be a problem?
Expert:  david craig replied 5 months ago.

its ok to have a little movement. but it should be rather secure.

Expert:  david craig replied 5 months ago.

any update?

Customer: replied 5 months ago.
Went to napa they dont provide the service
Expert:  david craig replied 5 months ago.

are there any other parts stores around? you may need to by a cheap code reader

Expert:  david craig replied 5 months ago.

any news?

Customer: replied 5 months ago.
Oops well i have that reAder, its not good enough? I just dont know all the functions and or what im looking at really
Expert:  david craig replied 5 months ago.

can you plug it into the dlc under the dash. key on.

Expert:  david craig replied 5 months ago.

do you still need assistance?

Customer: replied 5 months ago.
I can plug it under the dash, i was frustrated and went and bought plugs, wires and distributor cap, changed the plugs and the misfiring went away... but its still running rich it seems... im going by the smell from exhaust
Expert:  david craig replied 5 months ago.

Ok. good. does the code reader read live data?

Customer: replied 5 months ago.
I believe so, but I dont know what I'm looking at..... sorry for the delayed responses.. it seems to be running much better now after changing the plugs...
Expert:  david craig replied 5 months ago.

check engine light still?

Customer: replied 5 months ago.
Hasnt come back.. only thing is exhaust fumes still smell a lil rich... maybe it takes a bit for ecu to figure it out?
Expert:  david craig replied 5 months ago.

maybe, but that why i need you to read the live data to see what the fuel trims are.

Customer: replied 5 months ago.
fuel trims, ok I'll try to get u a screenshot of that.... at idle?
Expert:  david craig replied 5 months ago.

yes

Expert:  david craig replied 5 months ago.

Expert:  david craig replied 5 months ago.

Expert:  david craig replied 5 months ago.

Customer: replied 5 months ago.
Should i change the distributor and rotor? I havent done that
Expert:  david craig replied 5 months ago.

check the timing on that first. put it to tdc and pull the dizzy cap off and see where the rotor is pointing
