Hello. I am finishing the list of maintenance items on my car. I was on the last two things oxygen sensor and throttle body/MAF clean. I did the oxgen sensor and I gained 5 MPG everything went well. Then I took apart the MAF and throttle body and cleaned them with the appropriate things.
Here is where the problem is, I got a new gasket and put everything back together and started the car. It idled very high at 1500 RPM for a couple of seconds then dropped to a constant 1000 RPM and the engine began to shake wildly.
I double checked that everything was re-installed properly and found that the throttle cable had a little bit too much slack but adjusted it and I think it's back to normal. So I retried it and ended up getting even worse engine performance and a misfire code for cylinder #6. I checked all plugs, wires, and coils and they all checked out alright.
I am currently stumped and don't know what I could have done wrong in cleaning the throttle body and MAF sensor but now i'm stuck with a car that vibrates like crazy, and would appreciate any help I can get.
have the same problem?
