EVEN MORE 1997 BRAVADA PROBLEMS

It's pretty safe to say I will never buy another GM vehicle ever again. I have had more problems with this vehicle in the last 5 months, than I have had with all of my other vehicles combined, in my life. My wife told me it was acting funny, so I decided to "try" and drive it this morning to work. The P.O.S. light, I mean S.E.S. light came on a couple of weeks ago, but the vehicle had been acting fine. The last few days, my wife complained it was starting to act funny. I got about 5 miles down the expressway today and it starting spark knocking really bad and surging and bucking all over the place. I had a hard time maintaining 70mph. I exited the expressway and limped it home. On the way home I had a hard time maintaining 50mph. I would floor it and it would just spark knock and buck and not gain any speed. Sorry about the negativity, but I hate this vehicle. It's been nothing but problems. Anybody have any ideas? Two things came to mind right off the bat - bad gas or maybe a plugged up converter. But I really don't think it's bad gas because the S.E.S. light came on a couple weeks ago and the tank has been filled since. Please help if you can guys.

Well, I stopped at the local autoparts store on the way home and rented a code scanner and these are the codes it spit out:

 

1.) P0101 MAF or VAF CKT Range Perf

2.) P0420 Catalyst Efficiency Below Threshold (Bank 1)

3.) P1406 Manufacturer Controls Aux. Emmissions Controls

4.) P0300 Random/Multiple Cylinder Misfire Detected

 

The top three codes were displayed twice and the 4th code was displayed only once. Does anybody know what this combo of codes could mean? Thanks.

Hey dude,

 

Sorry I just got your PM today. I've been busy with other things lately.

 

That's sucks about your Bravada. You definitely got a bunk one! How much did the 'cat' set you back?

 

My blazer has been doing great lately. Haven't been paying too much attention to it though, I've been really busy with other projects.

 

Take er' easy!

 

Roland

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
