[silver bullit]

What kind of gas was you using, how much boost, mods?

 

[gotitjr]

I never really paid attention to the octane, but i use Chevron premium. All of the mods that i can think of are in my profile. I do have a stock smic, and plan on replacing it soon. I bought the car with everything done to it alreeady. I just bought a Hallman pro mbc because the one I have(ebay cheapie) does not work right. I have tried to lower my boost but cant get it below 19 lbs or so. Should I zero out all the values on my safc? thank you

 

[viprez586]

Research porting. Do you have an aftermarket downpipe/exhaust?
Sounds like your getting boost creep.
A common problem is the wastegate flapper not sealing with the "port" or "ring" on the turbo exhaust housing. It sucks I know, mine was pretty much gone and I could hit 20+ PSI on a stock setup. Look up VFAQ.com Excellent resource.

As for 43 counts of knock...could be from overboosting, or phantom knock.

Good luck.

 

[gotitjr]

It has a 3 inch turbo back. i think the cat has been gutted. I'm hoping the new mbc will help with boost. And my wastegate is dumped into the atmosphere

 

[HIGHPSI4]

Check the condition of your knock sensor too.

 

[just2asian]

I'm not surprised if that's just phantom knock, because if your getting that much knock I would think you could hear that.

 

[GVR4592]

It's not phantom knock, it's from over boosting. Research boost creep and porting.

 

[romeen]

Sounds like you may need a new knock sensor. I believe 43 counts of knock is what a 1G will show when the knock sensor goes bad. Do you have a CEL?

 

[gotitjr]

I dont have a cel on, i comes on when i start the car but goes off shortly. It did come on a once before when i was driving though. I have had the car running for about a month since I bought it. Clutch master cylinder went out after driving it ten miles. So I have been driving it like this for about a month, it does have a slight tick coming from the valve area. but that usually goes away after it warms up.

 

[GVR4592]

Sounds like you may need a new knock sensor. I believe 43 counts of knock is what a 1G will show when the knock sensor goes bad. Do you have a CEL?

That's not correct. 43 counts is the max knock count the pocketlogger will display. If the sensor goes bad it defaults to 9 counts.

That was starting off in third gear and going to fourth and fifth letting off until i could get the logger to stop. Would a FMIC help this issue at all being that it is like 20 degrees out? I know I need to get my boost turned down being as I don't race it.

 

[1gDSM4g63]

I'd be careful until you know what mods that have and are on you car before you take it all the way. And zeroing out the safc is going to make the car knock more. The high rpm need higher adjustments and there's something wrong with you mbc if cannot go lower than 19 psi.

 

[romeen]

That's not correct. 43 counts is the max knock count the pocketlogger will display. If the sensor goes bad it defaults to 9 counts.

Thanks for the correction Luke.

Do you think a bad ECU could be contributing to the problem?

I never really paid attention to the octane, but i use Chevron premium. All of the mods that i can think of are in my profile. I do have a stock smic, and plan on replacing it soon. I bought the car with everything done to it alreeady. I just bought a Hallman pro mbc because the one I have(ebay cheapie) does not work right. I have tried to lower my boost but cant get it below 19 lbs or so. Should I zero out all the values on my safc? thank you

Maybe you have unknowingly been putting in 89 octane. Maybe try some higher octane gas to see if that helps. It may help to diagnose the issue.

 

[GVR4592]

I wouldn't keep running it like that, you're going to pop the head gasket or worse. Do you know what size injectors you have? Can you post your safc settings?

Lets concentrate on getting the boost down to a reasonable lever before you attempt to do anything else. Disconnect the boost controller and bypass it for now. Run the vacuum line from the wastegate actuator to a pressure source on the intake manifold or the J-pipe of the turbo(not the throttle body). If you get solid boost around 8-12 psi, then the boost controller is the problem. If you still get 19 psi, it's most likely boost creep or a wastegate issue.

Another couple things that never hurt to do are check for boost leaks, and inspect your spark plugs. Make sure you have BPR6ES or BPR7ES gapped around .028"-.030".

Let us know what you find out.

 

[gotitjr]

Here in Evanston I believe we have 85, 87, 89, and 91 cotane. I know i have been putting at least 91 octane in. I just put new ngk plugs in gapped at .032", and new wires. I was told by Dsmdizzle that my injectors are the stock 450's, they have a blue top. I was checking things out and the timing was way off and one of the wires to an injector was loose. My lo setting are al close to +25, and my hi settings are around +15 i think. The cars engine internals are stock. No cc, ac, and all vaccum lines from the intake are all taken off.

 

[gotitjr]

Here are three quick pics of my engine.

Ok so I ran the vacuum line like you said. J-pipe on the the turbo(looking from front of car, left side top of turbo), to the wastegate actuator. My boost did not go straight to 18psi, it went to about 12 stayed there for a few seconds and then up to 18ish.

 

[GVR4592]

That's boost creep, you have a few options. You can try the peepers wga mod, or you can port the turbine housing.

Turbo Porting

 

[gotitjr]

Last night my car started missing real bad, like could hardly get past 2500 rpms, and was shaking real bad. I took a look at my injectors and on one of the the wires were loose and my timing was off real bad. I fixed both of those and it ran good. Then tonight it did it again except it is idling way rough and shaking the car. My wideband says it is really rich(at plus 25 at the 1000 setpoint on the safc, where it used to say about 12 on the wideband now is way rich). But anyway the car runs the same when i pull the #4 cylinder plug wire then put it back on, and it does the same with the #3 cylinder, But dies if i pull the #1 or 2.

 

[viprez586]

I see you're running a GM MAF, Do you have a translator? or just an SAFC. It won't work properly with just an SAFC.

If there is no difference when you pull the spark plug wire from the coil, its possible to say the coil is bad.
You can check the resistance of the coil to determine if it is bad.
To check secondary resistance probe the first two "ports" on the coil pack, along with the back two "ports" where the spark plug wires go. They should measure the same(roughly 10,300- 13900 ohms...again make sure its ohms.

Primary resistance is done by probing terminals(ports) 3 and 2, and 3 and 1. Primary resistance should be .77 - .95 ohms.

Once you have the coil situation squared away, run some NGK 6s part no 7131. and gap them to .028" you car will run way better.

Let us know what happens.

Yes I do have a translator. I know I am getting spark to those plugs, I also checked my injectors. My brother-in-law said I might have burnt them up but they are working fine. I will borrow a ohm meter, but im confused on how to do it, do I need to take yhe coil out? I will probably answer my own question once I go look though. Thank you

 

[gotitjr]

I did a compression test. In cylinder #1 and 2 there is about 130 lbs. And in cylinder #3and 4 there is maybe 7lbs. What do I do now. This is not going to be an easy fix is it, or could it possibly be a head gasket?

 

[tqmx1]

It's time for head pulling 101 It sounds like you blew a head gasket (if not more).
