Re: P0303 and Coolant
It's probable since you just replaced the plugs, that you got one that
is defective. I have seen this in the past. Change #3 again, check
wiring and coil connections (if present), clear the CEL and retest.
If you must flush, use very low pressure compressed air to clear tap
water out of the system. I've also pulled heater core hoses and cleared
them separately.
Also, this is a good time to drop hints that you need a good code
scanner, since Santa is generous this year.
