If input seals are leaking, then a quantity of air different from what the air flow sensor measures is entering the engine, and with this happening during the cold startup period when ...

Quote, originally posted by MRK Â»From the 2007 Vibe brochure, the GM Warranty includes an 8-year / 130,000 km coverage on catalytic converters and powertrain control modules (PCMs).

Quote, originally posted by Bectech Â» I'm long past my warranty period so I wonder how much the software fix would cost.Thanks for voting.If Vibe warranties are similar to Matrix warranties, then there may still be an 8 year (80,000 mile) warranty that covers major anti-pollution equipment. The eng...

Quote, originally posted by joatmon Â»I have heard, but cannot swear that the ECU program is different for Matrixes and for Vibes, and also that the ECU is not flash programmable.

Quote, originally posted by Neouka Â»I wonder if Pontiac will even offer it? It is possible that Vibe and Corolla share the exact same engine software and for one hour's labour time, you may one day be able to purchase the fix at a Toyota dealership.I can't see why Pontiac would deny its customers a...

Now for the news we all have been patiently waiting for since 2 years.The long awaited software patch was installed on my car last friday morning, February 9, 2007.It works.

UPDATE:Toyota Canada advised me today that the fix will not be arriving before the end of 2006, but in early 2007.The good news is that it will be delivered in the form of a software (firmware) update to the ECU.This would indicate that Toyota has done some serious research into the cause and soluti...

Quote, originally posted by stoutvibe Â»The rpm was surging up and getting cut back so quickly that the rpms were going above the normal 2300 to 2500-2600 from what seemed like just the momentum from the engine accelerating so violently.

Thanks for your two previous posts.Did that older 1980's Mustang (doing it in summer) have electronic fuel injection?

Hello again, it's been nearly 8 months since I updated this thread.Normally I would not want to bump it up to the front page until at least November, the month when the weather becomes cold enough to allow old and new members to be reminded that this problem is still there.In late June 2005, I recei...

Quote, originally posted by O_Positive Â»HOWEVER--I found the second time that the revving stopped when I let the clutch out about a half-inch.The reason the revving (pulsing) stops when you feather the clutch by a half-inch is that by doing so, you drop the peak idle rpms below 2300. I believe that...

Back again after a 7 month time out.This season it has been my car's turn to spend the night in the attached un-heated garage which is still slightly above freezing temperature, so I haven't had the car out in the cold yet.

Back in the mid seventies, I had a fairly new Cutlass that had a carbon build-up. What happened was that a flake of built up carbon broke loose but didnâ€™t get flushed out of the cylinder, or the carbon coating where the flake broke away from was very jagged. The net result was a serious case of pi...
