STARTERCABLE Posted January 29, 2012 Report Share Posted January 29, 2012 when i put the car in drive it stall. so i adjust the idle higher and it runs in gear but i have to press really hard on the brakes to keep the car from taking off. after 30 minutes or so of running the car stalls but wont start again for a while Quote Link to comment
KC Phirus Posted January 29, 2012 Report Share Posted January 29, 2012 Have you ever flushed your trans and given it fresh fluid and filter? Quote Link to comment
STARTERCABLE Posted January 29, 2012 Author Report Share Posted January 29, 2012 Have you ever flushed your trans and given it fresh fluid and filter? No i have not done that yet. I just worked out all of the fuel line and fuel pump issues, but I will try that monday Quote Link to comment
datzenmike Posted January 29, 2012 Report Share Posted January 29, 2012 The transmission is fine but too high an idle while holding it back with the brakes will over heat it. You need to strengthen the idle (about 750) to be able to keep it running in drive. Poor manifold vacuum will do this. Some things to check are The valve lash. Tight valve lash will hold the valves open and lower manifold vacuum. Do you have a Weber carb? These are notorious for the adapter plate coming loose or having a vacuum leak. Has a vacuum line fallen off? Listen for hiss when idling. With the engine fully warmed up, check or set valve lash, check timing set at 12 degrees* you need all three set before adjusting the idle mixture . Turn the idle speed screw while in neutral, down to 650-750. Turn idle mixture screw in and out to find where the idle is smoothest and highest. Turn in until quality drops, turn out until quality drops, select a position roughly in the middle. Likely the idle speed has improved, so turn it down and begin again, in and out to find the best idle quality, lower the idle speed. Repeat until you cannot improve it any more. This should give you a good strong manifold vacuum for the carb to work with and a proper idle air fuel mixture. See if it will hold idle in gear now. Quote Link to comment
DISLEXICDIME Posted January 29, 2012 Report Share Posted January 29, 2012 do you have point's ? what is your timing set at? any vacuum leek's ? is your air filter dirty? Quote Link to comment
STARTERCABLE Posted January 29, 2012 Author Report Share Posted January 29, 2012 can a torque converter cause a problem like this? Quote Link to comment
KC Phirus Posted January 29, 2012 Report Share Posted January 29, 2012 After you do all that you should still refresh the trans Or maybe it's 5 speed time. Quote Link to comment
STARTERCABLE Posted January 29, 2012 Author Report Share Posted January 29, 2012 do you have point's ? what is your timing set at? any vacuum leek's ? is your air filter dirty? the previous owner has all of the vacuume lines pluged Quote Link to comment
ggzilla Posted January 29, 2012 Report Share Posted January 29, 2012 Very, very common problem. Don't bother with changing the fluid or auto-trans adjustments. The two main causes are Incorrect idle-mixture adjustment or vacuum leaks. Best to start with a tune-up as Mike suggests. Set valve lash, then points dwell, then timing. For B210 with A14 automatic, set distributor timing to 10 degrees. Mike's process is the same as at the Tune-up tech article, but check for vaccum leaks first, otherwise the idle-mixture adjustment is for naught. It's all outlined step-by-step with photos at that tune-up link. There several things that can cause the engine to stall, so don't get discouraged if you don't clear it up right away. Just start with the easy things, then progress on until you fix it. Quote Link to comment

ggzilla Posted January 29, 2012 Report Share Posted January 29, 2012 can a torque converter cause a problem like this? Highly unlikely verging on near impossible. 100:1 it is not a problem with the transmission, but a vacuum/air problem. If the previous owner plugged the vacuum line to the transmission, that is a problem. Quote Link to comment

Start hitting up the junk yards yo! I don't know what part of bama you're from but I know personally that lower alabama has PLENTY of junk Quote Link to comment

datzenmike Posted January 29, 2012 Report Share Posted January 29, 2012 Usually it attaches to the same fitting as the thick hose for the brake booster connects to. May also be in line on that hose or at the one way valve on it. This is for an L series but you get the general idea. May be a combination of rubber hoses and hard lines going down over the back of the motor from the manifold behind the carb.. Quote Link to comment

ggzilla Posted January 29, 2012 Report Share Posted January 29, 2012 The AB valve is not related to Brake Booster. Get under the car and look at the automatic transmission. That's where the vacuum line is. Trace it back up to the engine until you find the other end. But why are you worrying about this? Go and fix your problem instead... stop asking questions and start doing :) But keep asking questions if you need clarification on anything. This can be a tricky problem to solve. Best to attach it methodically instead of trying 20 different things to fix. Quote Link to comment

STARTERCABLE Posted March 22, 2012 Author Report Share Posted March 22, 2012 can a bad brake booster cause the car to stall when i put it in gear Quote Link to comment
datzenmike Posted March 22, 2012 Report Share Posted March 22, 2012 Yes if leaking, so plug the hose at the manifold. If it fixes the problem then look into the hose or the booster for leaks. Quote Link to comment
