@JesseJames I was reading some advice to block the intake and if the car doesn't stall, you've got a vacuum leak. I tried putting my hand over the throttle body last night, but immediately pulled it away cause of the strong vacuum. Do you think it's safe to do that, or is the negative pressure dangerously high? If not, what could I use to block the intake?

Unless it is a very bad leak it won't stay running for very long anyway. I have a pretty busy day but I will find some specs for the maf and iacv and get with you on testing them later.

True or false: putting a performance carburetor on your motor can render your mechanical fuel pump insufficient, potentially necessitating an electric fuel pump.

<@&435155863217504256> Please have a look at my question when you get a chance. Thanks.

@Deleted User certainly there are carbs big enough that they will not be supported by the stock pump. But if your engine isn't a wildly built engine you don't need a carb that big. If you have a slightly modded or stock engine and wish to upgrade the carb chances are your stock pump will be ok. But they also make mechanical pumps that flow more than stock.

Sorry I have been out of town and not on my phone much.

I'm assuming there are no external leaks? I'm also assuming there is no gas in the oil? Also that is a returnless system right?

Try taking the filter out of the line and just running the line straight to the carb. I've seen a few filters suck air and cause this issue. I wouldn't think the carb would cause this issue. Honestly though I've never worked on many carb vehicles. All have been for hobby/racing applications.

I know a few old guys that I always go to for carb help that I can talk to tho. One is of the greatest generation and really knows his shit.

Still had the trouble then? If so that tells us it isn't anything from the tank to the pump or the pump to carb. That leaves the carb or pump.

Where the filter glass meets the end of the filter allows air in the system causing an issue like you describe.

Well I always remove the filter from the carb. But I thought u had an inline filter.

Yes try removing that from the system

I have seen it happen a few times. Once to me and when it does this the fuel doesn't leak out of the filter it just allows air in causing the pump to lose prime and therefor fuel psi.

Wish u was close enough for me to run over and check it out.

We would probably figure it out pretty quick on that stuff. I always know it all when I consume it.

That stuff was like water. I was scared to drink it because I thought I was going to accidentally die from alcohol poisoning

It could happen for sure.

Trying to change my wheel bearing for the first time on my own with a grand am. Any advice on changing it. Trying to avoid having to pump the brakes

<@&435155863217504256> ☝🏻

Well I just went ahead and did it and nowthis caliper won’t come off

To get the caliper off use a screw driver a big one to force the pistons in.

You should be able to find the process on YouTube.

I’ll look that up

@Pinochetball @JesseJames Got 'er fixed!! Took a chance on it being the IAC, went out and got a new one, threw it on, problem solved.

Ha!

Noice

That's great news!

Naturally it would be pouring

Any idea why tf this happened?

@ophiuchus what even is that? Is that your wheel?

Over pressurized tire?

Yeah it’s the tire

Wasn’t overpressurized last I check but damn

This is apparently blowout season. It can happen on under inflation to, or any puncture that causes a rapid air leak. That may be the worst ive ever seen

@JesseJames would know.

Bet he's seen a ton of blow outs

@ophiuchus I think under inflation. Causes a lot of sagging/wrinkling in the sidewall, drive it on the highway and that becomes rapid wrinkling and unwrinkling as the sidewall moves between the underside of the wheel where wrinkle is max and the top side of the wheel where there is no wrinkle. This builds up heat and fatigues the sidewall, creating a tear around the entire sidewall.

Unwind a paperclip, then bend and unbend one of the corners 50 times as fast as you can. You’ll be able to feel the heat generated in the bend and it will likely break through from fatigue failure. Same with rubber.

When is the last time you inflated that tire?

Here is an example of my neighbor’s tire, which was under inflated. I noticed and waived him down and got it replaced just before it would have completely let go.
