If your acura is backfiring and you have no compression in 2 and 3 cylinders what is wrong?

Most likely you have broken exhaust valves. If it is broken valves and you like the car a lot get your engine rebuilt. I got my '88 integra engine rebuilt for $3000 and it is running great. My neighbor found a mechanic that quoted $900 for his '88 Izuzu Pup and it has never run right.

How do you fix an engine with low compression in all 6 cylinders?
The repair depends on what is causing the low compression. Low compression can be caused by a blown head gasket, cracked cylinder head, burnt or damaged valves, worn or cracked piston rings, scored block cylinders. It's kind of hard to imagine that an engine would have low compression on all 6 cylinders unless something major is wrong, or the compression gauge is not measuring properly.
Your 98 ford zx2 is showing a cylinder misfire code and you changed plugs wires and coil what is wrong?
You may have a burnt valve or blown head gasket. Run a compression test on all cylinders.
What is wrong when a 1989 Pontiac grand am 2.5 pops through the throttle body?
that's not really a good question. it could be any number of things. sounds like its backfiring. this means that it could be out of time. could be a valve sticking. could be pushrod, or rocker issues. best thing to do would be a compression test on all cylinders, that would be a good start. dp the test dry, then wet, then post your results on here. somone might be able to give you a better answer from there.
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.
96 Honda Accord-chugs while running Thermostat has been changed after overheating Wassup?
Run a compression test to see if overheating has damaged the engine. All cylinders should have somewhere near 100PSI compression, but whatever it is, all should have similar compression. If any are significantly different, you've probably warped the head resulting in a damaged headgasket. That's the most common problem that is caused by overheating. If you don't have one or more cylinders with low compression, just try a computer diagnostic scan to see what kind of diagnostic codes have been stored. If you don't have low compression, the computer should be able to tell you what's wrong. God luck.
Why wont motor start with wrong firing order?
Because the spark plug must fire when the piston is at top dead centre of a compression stroke. If the plug fires when the piston is at any other position then you get backfiring etc and no start. The correct firing order ensures the plugs fire at the right time.
Whats wrong with 88 acura legend that runs rough 2 cylinders don't work the plugs do fire Car overheated That's when this happened.?
More likely than not you have blown a head gasket or cracked a head. Major repair.
What could be wrong with your 1994 jeep grand Cherokee 4.0 liter 6-cylinder if one of the cylinders has no compression and the others have 150?
bad valve, blown head gasket, warped or cracked head, cracked piston, or failed rings.
What else could be wrong if 2 cylinders are misfiring after getting water into the motor through the intake after the spark plugs and ignition coils have been replaced and it is still misfiring?
I really hate to be the one to tell you the bad news but it is possible that you have bent some valves. Take the spark plugs out of the missing cylinders and run a compression check on those two.
Why does your 1976 Dodge 318 keep backfiring?
Sounds like the timing is off or you have the plug wires connected wrong. Click the link I will post.
What is wrong with a truck that is backfiring?
If it is petrol then it is probably the ignition timing not set correctly. If it is diesel then it is probably the injection pump timing not set correctly
What kind of gas should be used for a Honda vtx1800?
My VTX1800 backfires quite a bit on Regular 87 I bumped it up to 89 and it cut out most of the backfiring....but runs best on Premium With a 9:1 compression ratio this engine should run fine on reg 87 octane fuel. An engine that backfires is doing so, not because you are using too low an octane of fuel, it is backfiring because the timeing is not correct or the plug wires are not connected correctly. They can also be a few other things wrong.
