94 del sol. D15b7. Had the issue a week ago and pulled the plugs. Found oil on top of plugs. I replaced the plugs and cleaned inside of the wires with brake cleaner. Car then started and ran perfect consistently for about a week and then the cold start issue started coming back and getting worse everyday. Today I baeely got her started and 5min down the road while taking off at a light it bogged out and died. First time its done that. Got her started again and rode high rpms in 2nd for a block untill I got to work.

Any help is appreciated.

 

Replace valve cover gasket, reset ECU maybe?

 

Yea I'm sorry I forgot to mention that when I replaced the spark plugs I also replaced the valve cover gasket as well as the spark plug tube gaskets.

The car is good to go all day once I start it and drive it to operating temp for a few min. But when she sits over nite and I come out to go to work I always have issues.

 

Quick update. Car died as i was getting off the highway. Bogged down tremendously and a homeless dude helped me push it into a lot. I pulled the spark plugs and 2-4 cylinder plugs were covered in oil on the bottom. Cleaned them off and car still wouldnt start. Had it towed home.

 

Then you need to replace the lower o-rings if there is oil in the spark plug chambers. Maybe the oil kept leaking in overnight so when you let it sit, a lot of oil gets in. It could also cause your car to bog cause its not sparking to ignite the fuel

 

Update- I feel pretty stupid. Previous owner had just over a quart too much oil in the car. Dizzy had catostrophic failure at the same time. Car is up and on the road
