What causes a 99 Saturn Sc Coupe when starting in cold weather start sputtering and shaking for a minute?
It may need spark plugs/wires. And while you're at it, run a compression test. If the compression is low in one or more cylinders it will make those cylinders less likely to operate properly.
Why does this Nissan altima only run on two cylinders when it has spark to all four and gas to all four?
You may have a blown head gasket. If you have a compression tester available, check compression on all four cylinders andcompare the readings. If adjacent cylinders read lower compression than the other two, it is likely the head gasket is blown.
Is there engine compression on a 1991 Mercury Sable 305 engine with the timing chain broken?
You may have compression on any cylinder where the valves happen to be closed, but you will not have compression on all cylinders. 1991 Sable does not have a 305 engine.
Why would a ford escort gt run on 2 cylinders and its not the ignition system?
It may not have enough compression on adjacent cylinders because of a blown head gasket or there may be 2 restricted fuel injectors or their may be a major vacuum leak.
What are the signs and symptoms of burnt valves in 1992 Chevy Astro van?
A miss on one or more cylinders and lack of power. Remove all spark plugs, remove the coil wire and run a compression check on all cylinders. The ones with low compression may have a burnt valve.
My 1986 Toyota truck is getting fuel and getting fire why will the truck not start?
You also need compression for the fuel/air mixture to ignite. Check all cylinders for compression. The compression should be higher than125 psi. You may have a bad headgasket.
Will low compression on all 4 cylinders of a 2.0 engine prevent it from starting?
The short answer is "yes". How low is low? And is compression low, and equal between adjacent cylinders? If you squeeze the radiator hose while trying to start the engine, can you feel pulsations? If the answer is yes to either question, you may have a bad head gasket.
If you drive your vehicle with 2 of the 6 cylinders only having 50 combustion how long can you expect the engine to hold up?
not long If you are saying that you only have 50 psi compression on two of the cylinders, then you need to find out why those two cylinders are that low on compression. You may have burnt valves, broken rings, or a blown head gasket. A blown head gasket is very serious and should be repaired ASAP. Stop driving the car until you find out why the compression is low.
120 lbs compression in cylinders is this low for 89 probe lx?
not if all the cylinders are even, you may have some leak down past the rings but unless your having differences greater than 20psi I would not worry
Under what circumstances may a laminectomy be performed?
Laminectomy may be performed when an abnormality causes spinal nerve root compression that causes leg or arm pain that limits activity.
You change the timing belt on a 1999 ford xlt and the truck still won't start?
Check the compression. If compression is down you may have put the timing belt on wrong. If it's down for only one or two cylinders, your engine may have damaged itself when the old timing belt gave out.
What is the PSI compression of a 350?
on average about 150 psi is considered normal. if you have more than 10 percent difference between the highest and lowest cylinders you may consider rebuilding.
