You’re correct, I am a poor student. I agree that the cost is high for a 16 year old car. However I have invested money in the car and do a lot of the repairs myself. I can take it next week sometime and get a vacuum leak test. I tried starting fluid and even used a propane torch and couldn’t find anything. I appreciate helping out money wise. As you said above, I have replace the sensor but it could perhaps be a faulty one. I’m on vacation for the weekend so I’ll be able to update once I get a smoke test done. Thanks again!
