    Same problem-Starts well, but while warming up loses power and misses underload, eventually settles down-ripoff mechanic diagnosed issue with wet electrics and catalytic converter-paid 200 but fault still there-I suspect auto choke/computer prob-any ideas?

Do you mean when the engine is running rough, you pull the 2nd lead out ther is no change in the roughness? If this s the case, then test the lead it might be faulty.

How to change spark plug on 02 mazda tribute


Is it a V6? For a V6 if you are standing in front of the car it will be the middle cylinder on the firewall side of the engine. You will have to remove the plastic engine cover and the intake manifold to get to it. If it were on the front side of the engine you would only have to remove the plastic cover. Since there is a good bit of work involved removing the manifold, I would suggest that you go ahead and replace all of the sparkplugs and consider replacing the coil for the one cylinder also. I have a 2001 Mazda Tribute. Mine started running rough so I decided to replace all the sparkplugs. After replacing the sparkplugs it continued to run rough. I took it to a shop and got it scanned (no cost for the scan). The scan showed the coil on the 3rd cylinder was bad. So I wound up having to pull the manifold off again to replace the coil :(
The first time it took me 1-1/2 hours to do the plugs, second time 1 hour to do the coil. Car runs great after coil replacement. Hope this helps.

Missing on the third cylinder. Were is that sparkplug located? 2002 ford escape.


Is it a V6? For a V6 if you are standing in front of the car it will be on the far right on the firewall side of the engine. You will have to remove the plastic engine cover and the intake manifold to get to it. If it were on the front side of the engine you would only have to remove the plastic cover. Since there is a good bit of work involved removing the manifold, I would suggest that you go ahead and replace all of the sparkplugs and consider replacing the coil for the one cylinder also. I have a 2001 Mazda Tribute, which is basically the same vehicle. Mine started running rough so I decided to replace all the sparkplugs. After replacing the sparkplugs it continued to run rough. I took it to a shop and got it scanned (no cost for the scan). The scan showed the coil on the 3rd cylinder was bad. So I wound up having to pull the manifold off again to replace the coil :(

Have Mazda bravo B2600 4WD ,has white smoke & oil from exhaust. Running rough as if on 3 cylinder


You dont say weather its a petrol or diesel engine as there a slight differance in the answer and if a turbo on a diesel thats even more of a differance, but taking it a petrol .
Well to start with the white smoke Isent smoke its water and after going through the engine it turns into Steam and thats what you see..
Running on 3 clyinders is caused through 1 cylinder isent working as a engine should and has a bad valve or a broken piston ring or more and even a cracked head and gasket letting the water through,,,also the broken ring works like a oil pump as if not firing given you power then it works like a oil pump and pumps it into the cylinder that dosent work only pumping oil into the hot exhaust system while running.CAUSING SMOKE
And if a turbo then could be the turbo bearings worn and pushing oil into the engine and still doing the same as before.
Let me know how you get on. RON

I just bought an 1993 mazda rx7 today but it wont start last


bastard things are prone to flooding im afraid, take plugs out,whizz it over for 30 seconds be patient and wait for half hour to give time to dry out, then a couple of squirts of oil in each plug hole, whizz it over for about 2 seconds,then a couple more squirts of oil in each plughole again,replace (dry) sparkplugs, leads on turn it over and it should go.ive suffered this twice this year (in the rain).
repeat if nescessary
avoid this problem by NOT RUNNING for LESS THAN 5 MINIUTS,as this is caused by a rush ov petrol because ecu thinks engine is cold so injects more fuel, then you turn engine off,this rush of petrol rinses the rotors clean of the oil they depend upon to maintain compression upon restarting, this is where the proceedure above works.
