foot to the floor and no increase of rpm

anyone either have a compression tester that is worthy or know of somewhere decent i can take it to either in bris or gold coast who knows a zed.

pm has been sent to eric awaiting reply from him as to when best suits him to check it out but if i can have it tested sooner rather than later is much prefered, cause if it's not a rebuild and just a injector it would be nice to attend the cruise

 

i have run a compression test these are the number I got

#1-180, #2-150, #3-150, #4 checked 3 times (1st time 80, second time 90, third time 80), #5-130, #6-130

 

looks like you found your problem, anything under 100 is hard to get to ignite.

 

Cyl 3 wasn't firing properly and it read 150.

 

we used a new snap on compression tester

 

Morning all I am a little confussed consult said # 3 was down 20rpm when it was stopped but compression test figures showed that #3 was at 150 (which is fine right) ? but compression was down on #4 80/90

I am still having the same problem as mentioned in my first post, i am pulling the cats off today to suss out what they are looking like other than that i don't know what else i should be checking

 

first up what is your firing order as you count, as far as I know it starts number 1 on drivers side at the front (for us RHD cars) number 2 is on lhs then number 3 middle RHS 4 and so it goes.

If I am wrong please someone let me know

 

i believe i have the firing order right

 

That's Right.

 

Sweet that confirms what I believed as well for firing order. As for your problem, how much did the other cylinders drop in RPM when you did the power balance test. we know that cylinder 3 dropped ~ 20rpm yes and if cylinder 4 is producing little or no power it should not have dropped at all but what about all the others. From what I remember (my consult cable is not running now so I can not verify) my power balance test tended to drop ~ 100 rpm to 150 rpm. Hopefully someone can clarify what the rev drop is on a good cylinder. I suppose I could manually check this however.

 

mc lovin will have to confirm that otherwise i will be doing another consullt next weekend

 

am also going to need new cats the old ones are stock where is the best place to get some new ones stock or not either or

 

i have taken the cats off and taken it for 2 drives and there was always power there nothing like i described in my first post but for a brief second it was a bit slugish around the 2500rpm once .

it appears to me the cat was stuffed but do you guys think by going off my compression test and consult i should be looking into it more than replacing the cats ?

 

i have heard others say that really bad/blocked cat converters can cause a major loss of power so definately worth looking into. as for actual replacement i would suggest deciding on what you intend to do about the engine before replacing the cats.

 

well idealy i just want to fix the problem i am having with it , for now .will worrie bout compression later unless that is the cause

 

with the cats on i had the problem cut in and out now cats r off yes it runs rougher than normal but it doesnt see to be having the same problem.

if i replace the cats and it stops having that particular issue i will be happy and will sort the engine when i have the $ to do so but right now cheapest option is preffered
