with results like that i'd say there are a few options:

1) your guage is stuffed

2) your cam timing is extremely out

3) your valves are not seating. at all.

4) you forgot to install piston rings.

it should be up about 150 or so for most petrol engines.

i have found opening the throttle body to make no difference, but hear you should do it?!

Freeman, your next step should be to do a leakdown test on the cylinder thats low, and that will tell you if its ok. 10% leakdown is fine.

RU34ME, how are you doing the test? how many times are you cranking it over before you take the reading?

Yeah i was planning to do a leakdown before i bought it but they didn't have the equipment on hand at the time unfortunately...

Hey are your plates SLY33? Mine are SLY25L lol.

Yeah opening the throttle body shouldn't make any difference

    • Jax Tyres Smithfeild Ive gone there a few time, well for tyres. on my 3rd visit I spoke to the dude and told how i just got slugged for rotors, brakes ect. His reply was golden; have you read whats on the front of the building. Never forgot it.       before picture, good friend got all these goodies installed.  Well time to study, servicing, maintenance all before this weekend driving lesson.  
    • Hello, first of, I’ve looked at many threads on this code but none have helped me, if you know one that will help me feel free to post a link.   Now to my problem. Recently I was driving and noticed the check engine light came on. I went home and did the test to see what code it gave. I got the 21 code but everything seems fine with the car, no misfire, idle is good, acceleration is the same as when I bought it. I mean no signs of obvious failure. If no misfire is happening I can rule out the coil packs right? Which is about 98% of posts saying it is. If anyone has had this happen and found the issues let me know please. No other lights are on.   The car WAS due for an oil change. I since then changed it so idk if that triggers code 21. Either way it hasn’t turned off.
    • Your both right, it may hold a bit longer then.  Soon I need to change the synchros, should I fit the billet plate while I'm at it? Or just a waste of money?
    • Some of the east coast US Stagea got together this past weekend at Lime Rock Park in CT for Grid Life Circuit Legends. This is probably my favorite pic of the shoot with @Morgan.Mundahl on IG. Hope we get more stags out next year! i think I spotted 5 other than my own at the event.
