I installed a magna II, MP plenum,#42 injectors. The sc ran fine for about 50 miles
Then the check engine light cam on at a stop sign.The idle went down to about
600 rpm and the check engine light cam on.Drove the car on home ran just fine.
But when I slowed down to pull into the shop the check engine light came on again
with the rpm slowing to 550 to 600rpm.
Ran the codes,came up with a 19-66.
checked all the wires,cleaned the MAF ,THE CID has only 450 miles on it.
I still have the stock fuel pump,but I wouldnt think that would affect the idle.
The sensors all have less than 500 miles on them.cam sensor replaced three times,
dis replace two times.cps less than 700 miles.
checked all plug wires they are working.
The codes i got were with the KOEO.
Have not takin the fuel pressure.
engine is hard starting after about 7 mile drive.
Where can I buy a fuel pressure guage that will screw onto the shraider valve ,and leave it there
all the time.So I can read it all the time.When the hood is open.
Any one have any ideas what I should look for and do about these two codes.
