Question about 1987 Honda Accord
My 87 accord starts but when i put it in gear it dies...Its carb and has auto trans
Probably a bad torque converter lock up solenoid...
Try starting it in neutral, and putting it in drive without your foot on the brake (I know the car will take off in quite a hurry if it doesn't stall but it's an easy way to check for this)
If it doesn't stall, apply the brakes, and if it stalls then, it definitely is a bad lockup.
I don't know if you're familiar with the torque converter function/operation, but where it is a fluid (liquid) and not solid coupling with the engine, lockup is used at certain road speeds/engine RPMs to get rid of the power loss that always occurs between the pump and the turbine of the torque converter. It mechanically (through transmission oil pressure) locks both parts of the converter together so it then acts like the engine crankshaft is bolted right to the input shaft of the automatic transmission.
But, as you might imagine, this system has to unlock the converter when you apply the brakes for the same reason applying brakes without the clutch on a manual transmission stalls the engine.
Bad lockup solenoid will cause this to happen... The converter stays in lockup and as soon as you try to stop the vehicle, you also stop (stall) the engine.
It also might be something else but I'd say I'm about 90% sure on this one.
