Re: catalytic converter? P0420 said by Anonymous_:I Tired Premium fuel and the code went away. That was for the long trip.
Tired with mid-grade fuel again code came back. interesting. $75 worth of fuel down the drain. I think the PCM was tunned for Premium fuel. Huge possibility. since it had 5 previous owners.
I just going to use up the tank and filler up with Premium chevron fuel.
If it has a tuned PCM, it WILL need premium fuel.
I would contact Miltzy motorsports (most likely the ones who tuned it) and see if they will send you a stock one aback in exchange for your tuned one. |

Interesting, you might want to take it to the stealership and have the factory tune put back in and go from there. |

Bet me! Bought it at a place called the Muffler warehouse in Ashland. $90 out the door. It's a universal heavy duty cat. Has lasted over 90k with not even a hint of a problem.

said by gillespie:I would agree if you get it at a big chain store, but they make high quality aftermarket cats that perform just as good if not better than the factory cat.
Not a chance. Not for anywhere near $90.00, that is for sure.

This is California we are talking about here. A aftermarket CAT is not sufficient enough for our tough standards.  |

FACTORY replacement is required to pass.
otherwise getting a after market is throwing money into a money pit.
Not true. IIRC Fed. law states that you must have a converter installed. It doesn't state anywhere that it has to be factory.
As far as an aftermarket converter, I got one from a place that only does exhaust. I got a heavy duty universal converter and installed it myself. That was roughly 90k miles ago and haven't had a lick of trouble. Now having said that, I strongly discourage you from getting one from Autozone or Advance auto parts. I guarantee you 'll have problems. BTW the converter only cost $90 out the door. |

By the way, did you ever get that cat dent out of your fender?
Yeah but it left a ruffle in the metal/paint
Now I having issue with the land owners dogs jumping on my car.
but if they damage it he has to pay for it or get it fixed, no more free passes.
Yes the coolant is Clear pink in color in the radiator.
I mix my own coolant 50/50mix
since premixed 50/50 is a scam , the non mixed makes 2 gallons for the price of one gallon 50/50mix.
50%/50% mix=12.99
100% coolant is 13.99 +1 gallon distilled water =0.99cents =14.99
=16.39 including sales tax
2 gallons of 50/50 is 29.42 including sales tax
since you are paying for only 50% of the coolant and the rest is water.
this comes out to paying 13.03 for just water and a bottle. |

Re: catalytic converter? P0240 said by Gordo74:What does the radiator cap have to do with the issue at hand? A good cleaning of it would have been fine rather than replacing it.
And you bought a thermostat just because they only had a few left in stock? You realize places like rockauto.com are cheaper and ship to your door, yes? Why buy something when you don't need it?
For someone who complains so much about how the car "costs you too much" (other thread), you sure do love throwing needless money at it.
Thermostat is going to be returned as the new cap fixed the issue.
If you see the rubber seal is torn and cracked .
That probably means it has a poor seal on it.
Car sits at the under the middle line even with the a/c on full blast.
Yes rocketauto is great but if you need the item by tomorrow it will cost the same or more to get it. |

said by rockotman:said by TA63:That killed the cat. I thought curiosity killed the cat.  I mentioned a failed cat that I experienced above. The dealer service manager at the dealer thought that a failed ignition module that I had experienced a few months earlier which turned my 4-cylinder into a 2-cylinder on Christmas day the previous year may have lead to my premature cat failure. As I loaded the family into the car on Christmas day to go visit relatives, the car ran extremely rough, so I parked it and we all jumped into my son's Scion to go visit family. I can tell you that 6'1" does not fit well in the back of a tC.  Anyway, the next day I dropped my "2-cylinder" off at the dealer (1 mile from the house) to get it fixed under warranty. It was, as I suspected, the ignition module. It was dumping raw fuel into the exhaust for only about the 5 or 10 minutes it took to get to the dealer. But the following March, the cat failed. replaced the radiator cap as it had caked on dirt preventing it from working correctly. I got a thermostat as well but I have not installed it Only got it because they only had a few left in stock.
coolant is clean so it does not need to be changed |

100% "clear" air comes from the tail pipe. a lot of it
before I was getting 22-23mpg highway
Now gas mileage shot up was getting 35MPG (300miles round trip total) (computer claimed 45MPG average though.)
80 to 99 (inst mpg) |
