I have a 1995 Chevy Blazer, and it has problems starting, idling is very shaky, and I smell burning all the time. I replaced the EGR valve, plugs, wires and caps, but was told the catalytic converter is now the problem. However, if that is true, why does the light only flash while I'm in idle?
if i were you i would have it checked for codes. somewhere you have a misfire. it could be something like the 02 sensor getting ready to go or the throttle position sensor. take it to auto zone and have them test it for you. it will save a lot of guess work.
you can get other tires as long as they are the same size.those are just what the factory put on them but you can go to any kind you want.
A flashing check engine light means only one thing - ENGINE MISFIRE. It is not the Catalytic converter causing it but this condition will destroy the Catalytic converter if not immediately repaired. Since you have tried the obvious things it is time to head for a service shop with the necessary test equipment to locate and identify the problem - sorry but it is time to open your wallet! However if the repairs recommended are substantially expensive . GET estimates! On any major repair I recommend that you get 3 or 4 estimates from local service facilities unless you are lucky enough to have a shop with an absolutely stellar reputation available. Compare the estimates and choose one of the middle estimates. My reasoning for this is the low estimate either left something out or worse is deliberately giving a low ball estimate to get you in and then when your car is all torn apart they find all sorts of critically important things wrong with it which run your bill through the roof. Do the leg work and be an informed car owner. No reliable technician or shop will give an estimate for repair site unseen except as a budgetary estimate which will be a range from the middle average to the unusual high end possible.
It flashes only when the computer detects a misfire. That's why it shakes at idle. Maybe a fuel injector problem. Good luck.
