Keep adding the Techron for a few tankfulls....It eventually will clean the injectors. My 'Service Engine Soon' light is on almost all the time, and adding Techron will not necessarily make the light go off, but you should feel a smoother engine if it does the trick. I would ignore the dumb lights on this car. My 'Low Coolant' Light has been on for years, and my coolant is FULL. Go by the feel and common sense with this car....I have read that one must wait a few refills of the tank before the lights will get reset, "SES" light goes off....This happens in my car. I have also read in your thread that removing the ground battery terminal for 15 minutes will also reset the lights.....haven't tried this but it is worth a try....good luck....

Replying to: ul00173 (Apr 27, 2008 6:36 pm) Does this make a difference? If ONE container of STP Injector Treatment in a tank of gas is good... would TWO containers in that tank of gas be better? Or would it be better to just use up the second STP container with the next tank of high test that I add? Someone told me that with all my "slow driving" around town and short trips to the grocery store, etc. I should take the Chevy out to the Freeway and "open her up" to 70mph for atleast five minutes. Should I be listening to stuff like that? And wouldn't ONE minute at 70mph be just as good as FIVE? |

I added it after adding almost a full tank of hightest but I don't think my tank holds more than 23 gallons. Don't know if one container is good why two containers wouldn'b be better though.

Replying to: 442dude (Apr 30, 2008 9:08 am) Its often the way that alternative products are "good enough" and sometimes even better than the brand names, but I have no familiarity with these particular products. > can't hurt to put more of either in but might not be any better either. Well, I'd rather waste five dollars as long as it "can't hurt". >Are you noticing more improvement? Since I am facing an otherwise catastrophic repair bill for a new engine, I am extremely motivated to "notice improvement". It may be illusory though. I don't know. I did determine that although it still stalls occasionally it seems to do so far less. I just drove to library, grocery store and post office, encountering several stop signs and red lights. It stalled only once and that was when I was already in the parking spot. It seems to run quieter but only slightly and I might be imagining it being quieter. I don't know for sure. I'm sure its still missing but maybe not quite as often. Just not certain about it. |

Replying to: 442dude (Apr 30, 2008 9:08 am) I went out prior to my being caffeinated to just lug some bags of garbage to the gate. No big deal. I probably wasn't fully awake. There was a bit of overnight glaze on the windshield so I started up the wipers figuring a few swishes and I'll see through the windshield more normally. There is this great big noise and something big and black falls off the windshield onto the ground. I figure something from a tree must have fallen onto the car but when I get out there is this two and half foot long tapered plastic/black-rubber thingie with a yellow placard on it: caution wiper system starts without engine running. Now remember, the hood was fully closed at the time. So where does the part go back to. As part of the oil change I think they check wiper blades. Did they remove something from the engine compartment but leave it up there in the wiper-well? Did it get blown off by the engine start-up? Or by my turning the wipers on? It seems to be from the engine compartment but with the hood closed, I think they never replaced it. Wow. I sure ain't never going back to that quick oil change place. But what about the 400.00 mechanic job? They never noticed it either? And I've been driving it around since? Just never used the wipers until this morning. Anyone able to figure out exactly where I put it back? Anyone think that mechanic was wrong to not notice something was amiss? |

Replying to: 442dude (May 01, 2008 4:16 am) Everything seems to be happening to it all at once. Now I get the 'Chand Engine Oil' message at startup ... and it just was changed!!
