By that I mean we sprayed the throttle body area 10 times. Out of 10 times the RPMs when up 4 times. It probably has some type of leak. He said it looked like I had a oil leak somewhere. I can't remember where he said he thought the leak was though. When I had my oil changed at the Chrysler dealership, they didn't mention a possible oil leak. I've had all the hoses checked at least 3 times in the last few months. They checked out okay.
Over the last couple of years, I have used the forum to self-diagnose my car. I have tried doing a couple of things myself or asked someone to help me. I'm a 52 year old female so as you can imagine, I don't do much auto repair. Below are a few things I have tried:
1. I disconnect and clean the battery connections twice in the last 3 months. Didn't help.
2. I Google searched and figured out how to take off and clean the Mass Air Flow Sensor with Mass Air Flow Cleaner (NOT carburetor cleaner). It took me a good 3 hours to do a job that would take a mechanic or any guy 45 mins. I don't plan on doing any more work myself. It's too darn frustrating and a lot of guess work.
3. 2 years ago my son replaced what I think was a cO2 sensor(?). It looked like a flat square, was about a $30-$40 part at AutoZone. I believe it was located in a place that was hard to get to on the driver's side. The replacement of this part helped the surging issue, but didn't not completely fix the problem. Over time, the car seemed to actually get better. Then about a year down the road, the problems started up again.
The surging issue comes and goes. Yesterday was the worst surging I've every felt in my car. Today the car drove just fine! However, I know the issue will be back.
This morning, I took my car into a local garage. A friend of mine recommended Gary D's Automotive off of S. Cooper in Arlington. I will let you know what I find out about the car. They are going to all me later today and tell me what they've found.
