Its me again :)

My 02 taco is having a difficult time idiling at stoplights, signs, etc...
It is running rough and acts like it wants to die every now and then.
I have ran 2 bottles of engine treatment through it to no avail...
Any suggestions?
Maybe plugs or wires?

 

Ya check your plugs and plug wires. Sounds like to me one of your plug wires may have got up against a header or something and is not making good connection now Also it might be a dirty MAF but i would try the spark plugs and wires first.

 

+1 when was the last time it had a good tuneup?

 

First check the plugs & wires....

You might wanna make a trip to Autozone or one of those national auto stores and see if they can pull some engine codes. Even though your check-engine light isn't on..... maybe there's a code stored in the computer that might be worth seeing.

You might wanna check your CAT to make sure it's not plugged...
Read this...very interesting.

Thanks a lot, just making sure I am not crazy

 

Not since I bought it a month and a half ago...
My brother in law is a mechanic and I am going to ask him to change all my fluids to synthetic

 

Thanks for the advice, I had not thought about the CAT
