#3563 of 3600 Spark plugs are burning lean by baytownmomma Oct 13, 2009 (6:42 pm)
I want to know what could possibly be the problem of a 1995 Mazda Protege burning lean when the diagnostic test says it is the 02 sensors and they have been replaced and it is still burning lean? Replies to this message: Mr_Shiftright (Oct 14, 2009 8:36 am)

Replying to: baytownmomma (Oct 13, 2009 6:42 pm) diagnostic codes only point to the system in distress. No computer yet invented for a car will tell you the exact defective part (in most cases). Many an 02 sensor (barrelsful?) is needlessly replaced because they are not properly tested after the codes come up. I don't know what code you got so can't say more, but things like bad/dirty MAF sensor, vacuum leaks, sticking injectors, etc. can all make the 02 sensor unhappy.   whoever "fixed" your car, guessed wrong.
#3565 of 3600 Transmission hesitates when put in drive.. by abner33 Oct 14, 2009 (5:41 pm)
I have a Mazda Protege ES with 55K miles on it. I purchased it new. It has always been garaged. Recently every morning when I get it, I put it in reverse and back out into the street, stop and put it in drive. The car will hesitate for about 3 -5 seconds and then go in gear and everything is o.k. for the rest of the day. This happens every day. I had a transmission flush and fluid change at the dealer, but it didn't help with this problem. Any suggestions are appreciated.   Thanks, Abner33 Replies to this message: autonomous (Oct 15, 2009 1:44 pm) abner33 (Oct 15, 2009 1:58 pm)

Some garages can get quite cold overnight and cars react to cold weather. You may want to give it a few more seconds to warm up to see if this helps.

Replying to: autonomous (Oct 15, 2009 1:44 pm) Thanks for your reply and suggestion. I don't believe the weather is contributing to the problem. I have been experiencing this problem for about a month now. During that time we have had very warm summer type weather and even though we are having lower than normal temps now, it hasn't been below 50 degrees F.   Abner33
#3568 of 3600 rich burning spark plugs by baytownmomma Oct 17, 2009 (5:53 am)
I have replaced my o2 sensors, sparks plugs, wires, rotor, fuel pressure regulator, had throttle body cleaned, and my car is still burning rich. Took it to repair shop and the code comes up PO1170 changed sesors but the problem still exist. Checked the hoses for leaks and there are none. What could it be?

Replying to: baytownmomma (Oct 17, 2009 5:53 am) According to an OBDII website, the code P1170 in the case of Mazda vehicles indicates "HO2S Bank 1 Sensor 1 Circuit Fixed (Bank 1 Sensor 1)". I'm not sure this explanation helps to make things clearer.
#3570 of 3600 burning rich by baytownmomma Oct 19, 2009 (12:17 pm)
No this does not help because with that code we have changed both sensors and my car is still making my spark plugs black with soot and we have changed filters, plugs, fuel pressure regulator, fuel filter, wires and the car is still burning rich. I dont know enough about the fuel injectors. I wondered if they were bad would that make my plugs soot up or even the EGR? Replies to this message: autonomous (Oct 19, 2009 1:42 pm)

I had a diagnostic thru two shops and that code PO1170 is what was given and the car is still burning rich. Running out of optins. Replies to this message: autonomous (Oct 20, 2009 2:24 pm)
