2006 gl8 Throttle

Solve the idling jitter of Buick Luzun engine, the computer detected a fire in cylinder 5, and the computer showed a normal fire when the speed increased. The cylinder pipeline and spark plug are newly replaced. What should I do? 18099250992 may be sensitive to updating sensor data together, which is a good thing. Sensitive sensors can protect the engine and prevent it in advance. If this kind of jitter can clean the lower oil circuit and add two kinds of general fuel additives to the oil tank, the oil jitter will basically disappear after running two tanks, which is very helpful for the advanced sensor data and avoids the long-term poor combustion and high temperature affecting the engine performance. If idling jitter occurs, it may be that the throttle valve is too dirty and needs cleaning, or the engine foot pad is damaged. The joint between the engine and the frame adopts an organic floor mat, which can absorb the vibration generated when the engine is running. The machine pad is rubber, which will age and harden when used for a long time. If the foot pads of the machine are aged and hardened, the engine will shake when running, and passengers on the bus will feel a little grateful, that is, the five cylinders of the camshaft are worn and the tappets are worn. Just these two, the price is high. LZC's LZC engine is very troublesome. Try not to move the engine, camshaft and camshaft bushing, which is more troublesome. Movement is not a small number to measure cylinder pressure. Thank you, but all five cylinders of the camshaft are worn, and so are the tappets. Just these two, the price is high. Is there something wrong with the engine camshaft of LZC? Thank you. Only the five cylinders of the camshaft are worn, and the tappets are also worn. Just replace these two. Price is high. LZC's engine estimates that there are many problems with the valve by measuring the cylinder pressure, or there are problems with the cylinder gasket. Measure the cylinder pressure. Didn't the camshaft shake before the problem occurred? It was not until this time that the cylinder head gasket was replaced that it shook @20 19.
