So this problem started off kind of randomly and it is becoming more and more frequent. It usually happens after I have been driving around for a little while and occasionally it happens after its been sitting all night. I start the car and it idles horribly. It feels like the rpms are running really low (don't have a tach so I'm just going by sound) and the engine shakes as if it is missing or something (sounds kinda lobey). Sometimes, it will idle so bad it dies and I have to start it and give it a ton of gas and then it will smooth out. Today there was a little bit of white smoke that came out of my exhaust. Once I get going, it runs like a top. Even if I come to a stop...the idle is really smooth and we're firing on all four. It only happens after I have turned the car off and am trying to start it back up.

Recently I replaced the plugs, wires, distributor cap, rotor, radiator and did a valve adjustment. I have a cold air intake that's been on there for years. It's a D15B7 with 250,000 and everything is original.

sounds like its missfiring at the beginning. although you replaced the dizzy. cap see if the electrodes are still good and clean.
250k, sounds like its on its last leg

I don't know about last leg...its a bit of a tank, haha. If I can find what's wrong, I can fix it.

Aside from corrosion on the distributor, is there anything else that can cause a misfire? Could I possibley have a leaky fuel injector or something that's flooding a cylinder? Or maybe a sticky valve? What are my options?

rick_rabies

possibly. pull your injectors and clean them up good.
put a can of seafoam in the tank with a half tank of gas


did this start when you did the tune up?
dif plugs can cause it as well. did you gap them correctly?

mss8rc

No it's ran perfectly since I have done the work. I did all that stuff back in December. Yeah I gapped them correctly. I guess I can pull the injectors and see what they look like. It might be a while before I get a chance though because I have another project that needs attention first. I'll let you know if I see anything.

Well I put a can of sea foam in and it seems to have fixed it. I've started it up now multiple times the past few days and it runs fine every time. I did notice my coolant was running a little low and it looked like there may be some exhaust in the coolant. I'm guessing that means I have a head gasket replacement in the near future...
