Start by doing a compression test, could be a bad head gasket. i assume its a typical mid 80's carburator with a mess of vacuum lines. so you dont have to worry about trouble codes or a mess of sensors to throw parts at. since you just did a tune up i would check the distributor hold down and make sure you got it tight the that it didnt walk out of time on you some. typically white smoke usually means either a bad cat or water getting in the motor. less likely but probable is the choke is stuck on. hope this helps, good luck!

SOURCE: my 1999 nissan maxima has a rough idle and some time dies at idle

It may be throttle position sensor or camshaft sensor. Most likely the throttle sensor.

SOURCE: rough idle, dies when trying to give it gas

it'll either be your ignition system (spark plugs, distributor cap, etc) or more likely your fuel system (most likely your fuel pump or your fuel filter)

While driving my dashboard displayed the warning sign for oil. the oil level was correct, but still it is rough on idle and makes a lot of smoke. how may i diagnose the problem?


Bummer deal! Rough idle and black smoke indicates a possible bad fuel injector leaking gas - or failing spark plugs. Bad or dirty injectors are a cause of sticky valves, and when sticky do cause rough idle and sometimes valve tapping - beside black smoke. Check those items first as they are most common failures. Rarely, a engine head sealing gasket may leak coolant into the motor to cause such problems. That would make a white steamy smoke. In that case it would overheat - did it? In this case, serious engine work, or a new engine is needed. I like the products at this web sites to end those issues. Hope this helps.

Idles rough and smokes when first stated


Worn valve guides allow oil to drain into the cylinders, causes blue smoke, fouled plugs will idle rough.
Coolant in the cylinders from a blown head gasket will cause white smoke.

Replace your hose going from intake to brake booster ( vacuum leak) check all other hoses also. Clean the throttle body. And a tune up probably wont hurt either.

Could be a idle air problem. The injector could be leaking when you shut it off ..Try some injector cleaner see if it gets better..The idle air shouldnt run rough just idle real low or sometimes it will get stuck and idle high....Are you losing any antifreeze..If you are the 2.0 SOHC engine bad about leaking antifreeze into the cylinder and makes the engine run rough until it burns it out..See if you can see the smoke coming out when it happens..White smoke indicates antifreeze,,Black smoke indicates fuel..

A bad coolant temp sensor for the ECM will cause that problem ... they are cheap and easy to replace. One other possibility is a piece of carbon stuck in the EGR causing an internal vacuum leak ..
Good luck.

The ck engine light should not be ignored, what sensor was shown to be bad ? Have it scanned again and replace the sensor that is bad if it still runs rough you might want to consider a tune up. Plugs, wires, fuel and air filter's and clean the throttle body with some gumout. It could also be the IAC motor Idle Air Control. Good Luck
