well iguess thats that did the compression test warm on #1&#7 120 still

 

good morning just a quick opinion here....is there any benifit to doing the cooling system pressure check at this point i will have to drive a half hour each way for a test kit i have no evidence of anti freeze in the oil and no overheating when running just the low pressure readings in the left bank thanks for any suggestions

 

Are you still chasing the misfire? Do you feel the misfire, as in the engine running rough? Another member told me about a technique he calls baptizing.

Poor water around all the fuel injectors while the motor is running, if the roughness/misfire goes away you need to replace your injector o rings.

If you have the money, buy a pressure tester on eBay. Around $100.

 

hi yesthank you for your reply almost dont know it at idle only under load and acceleration no vapor in exhaust and oil clean what i came up with as a guess pulling upper manifold question the bracket thats in front of the secondary air passenger side do i have to remove that metal line from the manifold or can i wiggle out

 

Not sure what metal line you are talking about. You should only have to remove the nut/studs from the SAI connections to the manifold.

If you are talking about the throttle cables, yes, unbolt bracket and put to the side.

 

got it double nutted the stud

 

bit out of practice did a lot of engine work in my 20's and imported them a long while back but its coming back im aaaaaa better than 3 times that now

 

ok upper manifold is off...........question is do i just do the o ring seals or replace the injectors on those two cylinders whats the experience here?????

 

gooday i have ordered a leak down tester so hopefully can diagnose things here before going any further........i would think i could bubble check the injector o rings while the the cyl is under pressure ???

 

You could, in theory. A little unorthodox, but it seems feasible.
