hello, i had a similar case with a tr6 car that had been so messed up with vacuum lines capped. car will run but badly check oil and all fluids/get the lines fixed
Zero degrees at 500 rpm with vacuum advance unhooked and plugged and transmission in drive.
Plugged fuel filter? Plugged air filter? Plugged catalytic converter?
Plugged oil pump screen,plugged oil pump itself, broken drive shaft for the oil pump ,broken drive coupler for said pump. no oil in oil pan .plugged oil passages in engine block.
i drive a car, so emissions are damaging the environment
Could be a lean condition. Check all vacuum lines.
I am trying to figure this out myself. I have a 96 Chevy S-10 Blazer and I believe it is the vacuum acuator located under the battery box in the engine compartment.
It could be a problem with the front hub vacuum system not pulling a complete vacuum. I have a 2000, and while researching another issue I learned that there is a vacuum pump behind the bumper to lock-in the front wheels.
A plugged transmission filter can cause your transmission to hesitate when you shift into drive. A collapsed vacuum hose can also cause the problem.
You can hook a vacuum gauge to a direct vacuum source on the intake manifold. There's several vacuum ports on the intake. Gauge should read at idle 18 to 21 inches of vacuum, the higher the better. If it has real low readings like below 18 Then if you KNOW for sure there's nothing else wrong with the engine, then it's probley the converter.If you want to KNOW for sure then take the exhaust loose on both sides of the engine and go drive it. If it run's good and you like it, then put a converter on it.
Under the battery tray. The battery and battery tray needs to be removed to gain easy access.
a flash drive
there is no drive cycle for a catalytic converter it could be plugged up....
