Everytime that I press on the brakes and my truck is moving forward the truck stalls. I had just a few days before fixed the vacuum leaks when this started happening. Afterwards I reset my holley carb to the factory fuel mixture needle settings which fixed a lot of performance issues but then I was driving about two hours later and started having this problem.

I had a previous post about this issue, and I disconnected the vacuum line from the intake manifold and tested it, and although it took much longer for it to kill my engine(I was almost completely stopped from 20MPH) my truck still died.I also checked my vacuum.26"

My truck has a 5.2L 360 from a 1987 ramcharger, if anyone knows what could be causing this, please reply because Im out of ideas.


Thanks for your time

Check the PCV valve/EGR valve and the brake booster might be leaking, also the idle air control valve and throttle position sensor-

My engine has a holley carburator. And also I started the Engine and then I shut it off and removed the hose to the vacuum booster thinking that it would still give me a couple more power assisted stops. But when I started it up a second time no power brakes at all. Is this normal? If not then I know that the vacuum booster must be leaking because I just put a new check valve on the booster

To check the vacuum booster, pump the brake pedal with the engine off until you've bled off all the vacuum from the unit. Then hold the pedal down and start the engine. You should feel the pedal depress slightly as engine vacuum enters the booster and pulls on the diaphragm. No change? Then check the vacuum hose connection and engine vacuum. If okay, the problem is in the booster and the booster needs to be replaced.

I tested my vacuum booster as suggested and the vacuum booster is fine.I pumped the brakes with the engine off until the pedal was really stiff, then as soon as I started the truck the pedal sunk. If its not the booster then what could it be?

I thought that the torque converter clutch solenoid is only on automatic transmissions and mine is an manual.

I think it has something to do with the fuel level in my carburetor and then when I push on the brakes the fuel pretty much floods the engine. My fuel pressure was high (about 10psi) so I lowered to as low as I could About 6 psi. And it still will die but not as fast the only problem is that I would adjust the float level but there is no way to do that on my carb."Next Gen" new needle and seat design crap. What else can I do?
