04 GTP- starting issue

**jmsgtp04** · 09-23-2014

I have an 04 GTP (all stock) I know I have a po420( catalyst efficiency) check engine light. (i am going to try the downstream 02 sensor cause the upstream did nothing)
I also have issues sometimes getting it started. I sometimes takes a few tries with finally a little on the gas pedal to start. After its running no other issues. Any one have any ideas? Thanks.

MAF?
Downstream 02?
Plugged cat?
Could all be causes of it not wanting to start I do believe =o

With a little research you'd figure out the hard starting. It's super common issue on DBW throttle bodys. It why they make forums, to have the info out there.

Clean it and MAF and it'll start like a new car again.
