I might need to get some of that spray, one thing I did notice is the fact that when I accelerate the car will not take off. It just revs without taking off as before. I did had it shut off on me/rough idle while I was backing up to park. Not sure if I should suspect a vacuumed leak, not sure how the timing got off as I have not touch the distributor cap. I wish I can do it but I might have a mechanic do it. The smell of raw fuel is gone from what I can tell. The EVAP monitor settled in after refueling the car, all I need now is the o2/EGR to settle to have them settled in.mdmellott wrote: ↑Thu Jun 15, 2023 8:21 pmThat's a huge improvement with the STFT for just unplugging and plugging back on the connectors. The harness connector contact pins may need a bit of cleaning with a shot of electrical contact cleaner spray to keep it right. The only other detail I would dial in is the ignition timing advance. At 7deg while idling, it's quite a bit off from the 13 to 17deg specification. Starting to look good though. Still, take a look at the fuel regulator vacuum line to see if it has fuel dripping from it, as VStar mentioned.
Sorry, it is more like the engine feels sluggish, wonder if it has to do with the spark adv been at 7 degrees vs been at 15 +/-2 normal range. I did refuel on Wednesday and notice 2 days later that it burned 1/4 tank already. How can I correct the Spark Adv to be at its normal range?VStar650CL wrote: ↑Sun Jun 18, 2023 6:37 amIf the engine revs normally but those RPM's aren't being translated into movement, that's a transmission problem and not the engine.
Thanks for the info, I think I am going to take it to a mechanic. I am tempted to see if I have a vacuum leak somewhere if that is the case, not sure how I went from 15 down to 7.VStar650CL wrote: ↑Sun Jun 18, 2023 3:14 pmToo much advance will make the ECM dial back the power when it detects knock, so that could definitely limit your performance. You'll need a timing light to set it up perfectly, and the engine must be at the proper idle speed defined in the FSM. However, you can get it close just by turning the distributor and watching the realtime value on your scanner. If it's close to right and you still have power loss, then it's likely the problem is elsewhere.
An old timing belt that has been stretched and worn old with age, will retard your timing.jetstream87 wrote: ↑Sun Jun 18, 2023 8:07 pmThanks for the info, I think I am going to take it to a mechanic.

Ugh!!!! So I have not gotten the chance to time the car properly - however the car decided to act up on the way home!mdmellott wrote: ↑Fri Jun 23, 2023 11:27 pmAn old timing belt that has been stretched and worn old with age, will retard your timing.jetstream87 wrote: ↑Sun Jun 18, 2023 8:07 pmThanks for the info, I think I am going to take it to a mechanic.
