So today when starting up the car up for work I get a very rough idle..
engine light starts flashing so I check the codes.
Engine idle smooths out .
Code reads p0300, p0304, p0305, p1319, p1317 p1316.
I clear the codes. Car drives fine no lose in power.
Sometimes rough idle on start up but that's it.
The idle smooths out after about 30 secs.
97 50k miles,
Just had the coolant tank replaced and water pump and drive belt replaced as well.
Any help guys?
