Rough Idle. Is the ingnition timing electronicly controlled?
Hi guys. My girlfriend has a 95 mazda protege. It is idleing pretty rough but fine at all other engine speeds. I changed the spark plugs but that didn't help. I cleaned the throttle body out and it was pretty dirty and it helped a little but not much.
I'm thinking of doing a full tune up but was wondering if the timing is electronically controlled or if it has a cap and rotor i need to replace and manualy set the timing. the car has 114K miles Thanks for the help. |
Yes, you have to set the timing manually with the help of a timing gun. Other things to consider when experiencing rough idle are:
- Fuel Filter - PCV Valve - O2 Sensor - Air Filter - Spark Plug Wires What was the condition of your old spark plugs? Regards, Oz |

Originally posted by Audi2Honda I don't remember the condition of the old plugs. I assume the O2 sensor has a maintance schedule right? How much does one of those cost and where can i get it. Its located right after the exhaust manifold correct? As far as I know, we only have one (1) O2 sensor located just below the exhaust manifold heat shield attached to the exhaust manifold downpipe/collector. You might get away getting a Bosch Universal O2 sensor which costs around $20-25US. Or get a Direct-fit (probably from Bosch too) around $50US. Shouldn't be too expensive. Regards, Oz |
