Hey guys, My rx7 is a 93, bone stock other than basic upgrades such as intake/exhaust etc. I've had it for awhile now and i know it's relatively normal to have a bit of a sputtering idle, little tiny pops and backfires but just recently it's been getting a little bad. When i first start the car up from cold and or already warmed up it smokes a little bit, (white smoke =/) and then it goes away. it's not a lot of smoke but enough to make me wonder whats causing it and at idle she sputters and pops a little more than normal. Any ideas and or suggestions? Like Maybe do a plug change? i did do the plugs about 1200 km ago. Or would a plug wire change help? I was thinking of getting my injectors cleaned as well. Anything would help. thanks everyone

 

It's still probably just condensation, especially if you're starting it up cold in the morning.

If you're not losing coolant or finding exhaust gas in the coolant, don't worry about it. Coolant seals will smoke in most cases during a hot restart.

If you get your injectors cleaned, do it and get some miles on it before storing for winter, or put the job off until spring. Freshly cleaned injectors should be installed and run within a couple of weeks or you run the risk of them sticking or functioning poorly. I learned that the hard way -fortunately the resulting fuel supply issue did not damage my motor.
