Changed my air filter...?
Changed my air filter...?
Hey Guys,
I changed my air filter and in a few days I got the check engine light go on. To lean, bad gas, air leak at the manifold, and bad o2 sensors.
What did I do wrong? Loose MA? Love the car but the air filter seams a little weak to me.
Thanks for your help.....

Re: Changed my air filter...?
When you say "air filter" do you mean air filters? on the N/A there are two filters, one one on each side of the engine cover/air filter box.
You do have to seat the rear of the box on the T.B. and make sure the it has sealed properly (rubber ring), then tap the front end down.
However, I'm not sure that alone would cause the check engine light on, have you read the codes yet to see what is not working correctly?

To lean, bad gas, air leak ...... are they problems you have or guesses?
Confused, sorry.
Re: Changed my air filter...?
Yes, two filters changed, sorry bout that. I had the codes checked and it had three different code numbers which I did not write down. Standard o2 sensor to lean code, code for bad gas (which I can rule out at this time), and a leak in the manifold which would be I guess, air intake valve or the mass air flow sensor.
I am going to check the connection to the air intake valve and the ma sensor this week-end.

Re: Changed my air filter...?
The throttle body was loose, the bolts were not very tight. I cleaned the tb and replaced the o-ring. Pushing down on the airfilter must have broken the seal made by the silicon gasket causing a small air leak. $18.00 for the o-ring. I did not use any silicon gasket material, o-ring only.
Re: Changed my air filter...?
JL,
The "check engine" light comes on for any number of reasons. Leaving the gas filler cap lose will also cause the check engine light. I know you just changed both filters and found lose carb in the process. Just don't limit your focus to the filter change.
Here's another good site to bookmark as well.....

Auto zone checked the codes for me. To lean- bad gas, o2 sensor, manifold leak. I replaced the lean o2 sensors and changed gas stations. The only thing it can be is a manifold air leak. All the other cars I have owned had clamps at every rubber joint. I will check the codes again but I think it is a leak.

In case you are not familiar with this, you use a UNLIGHTED propane torch around all the places there might be a leak while the engine is idling, if the idle speeds up, YOU FOUND IT !!!
( if you are a smoker, it is not advisable to do so while running this test )

The latest... I have had the TB off four times, bought (2) TB o-rings and (2) rear O2 sensors. I bought hose clamps and clamped every thing I could on the funky TB hose assembly. Tripped the service engine light and drove it 35 miles and the light came on again. When I started having problems with this was after I replaced the air filter and the car sit through the winter and I started driving it this spring the light came on for the first time. I decided to change the air filter and bought a different brand Nappa. I tripped the light and drove the car 60 miles and the light came on again. I was going to take it to have someone look at it. First I decided to drive it to our family reunion which is 600 miles, light was on. I came home and it sat overnight. I took it out for a short drive the next day and the light was no longer on. I have driven it a couple of hundred miles and the check engine light is still off.
