Hi Gents, my service engine light did finally come back on despite me clearing it with the machine and replace the gas cap. So I borrowed the machine again to further see if I could have it further show me more details / closer to the point as to what my actual, problem for light being on.

So I have light on and gas station pumps shut off continuesly if I try to pump at full speed. And I guess for a few years I could feel at times while driving a small surge of gas or power off and on. May have been around for as long as that light as been on in my car , ??? not 100% sure .

I did notice last night , I set my car on cruise just a hair above 80 KLMS , so I could pay attention / watch my RPM make eratic jumps. Say from 1500 to 2000 rmp and sometimes 1500 say to 1700 as example. I do not think I felt any surge in gas / speed as it sayed on the jsut above 80 KLMS I set the cruise at.

So are all these things one in the same and reason for that light being on ?? I went threw many sections of the machines sections etc. I took photos step by step for each section and or procedure. But honestly gents I don 't know what to make of the info I saw.

OTHER then one test section > SCAN COMPONENT TEST PROCEDURE of these 3 items >> FUEL TANK PRESSURE SENSOR & EVAP CANISTER PURGE VALVE & EVAP CANISTER VENT VALVE, ( funny I believe they all ready ALL the exact details / info for each of those 3 parts ), and one thing sort of stood out to me and said EVAP Fault History ( flashing back & fourth )>>> Small Leak then Weak Vac . In all my checking with this machine I just do not understand the Percentages % they show in areas, and what any of the number they show in areas, and when it uses the words YES or NO or CLOSED or OPEN.

So is there any one of you nice gents I could email the in order photos I took ( serveral of them ) so that you can read / interpet things and help me understand things more / better.

If you have the small leak evap code coming up on a car as old as your 2k or my 99 it is probably the filler neck leaking. I changed both the valves on my car and i have new fuel lines and a new tank and the code was still driving me crazy. I thought my neck was in great shape after sandblasting and painting it but it turned out that they leak where rusts forms between the plastic on the end and the metal the neck is made out of. Maybe you can try putting some sealer there temporarily to test it.

Ya might try that caulking of the neck. Again with my luck it won't be that easy / cheap of a fix. LOL.

I'll bet it is the filler neck and you can buy it new for around $65 on Amazon. It drove me crazy and i even tried smoking it and i couldn't find the leak. Someone i know had one go bad on a 99 malibu so i figured i would try it and it worked. The tube looked so good unless you look real close and see the pitting where the metal contacts the plastic piece that the cap seals on.

I bought a Dorman 577915 filler neck from rockauto using a 5% code that made them the cheapest. Current promo code is "107703168845393". It is $47.79 before shipping and the promo code.
