we just cut the cat off my friends Chevy Baretta after it was doing the same thing and now it actually wants to start on the first try and idle. then we replaced the muffler and it runs even better.

 

i was wondering if could be osetmhing iweth distributor or the timing?.............i would not liek to remove cat becuase my car is already to loud as it is......

 

could be the O2 sensor, have you noticed a big dip in you gas mileage


edit i finished reading you post. i say its your o2 sensor

 

thanks for your help i will buy a o2 sensor and tell results..........and get a new cat............thx

 

bump cause i have same problem with my h22.

 

i do not know what ot start with first..........shall i buy oxygen sensor cut off cat
reply i need help

 

change o2 sensor sounds really rich

 

what do u mean by rich....... and were is cheapest place to get 02 sensor i found place narme for 74 dolloars anywere cheaper!

 

could the o2 be bad still even though i dont get a cel for the o2?

 

just disconnect your cat just to check if it helped or not....I would probably try the distributor rotor and cap....see if there is something going on there...

 

I would place this as the 02 sensor fouling and then causing the car to run rich. In turn it likely clogged your catalyst. As for burning oil, if your getting up there in mileage you may be getting some blow by in the cylinders. Run some Castol GTX 10w-30 with a Puralator (PureONE) filter and see how you do. Check you oil at every fuel stop on the flat surface by the gas pump and wait about 3 minutes before checking it after shutting off your engine.

A cheap 02 sensor and cat can be had at any autozone and installed by hack mechanic anywhere all for under $250.
