Hi Guess it is an automatic trans. I would check trans fluid first. Make sure you check the right way. Most have to be in neutral. It will tell you on the stick. If fluid is good, will need torque converter, modular valuve or to be rebuilt. Unless the screen is plugged. Could try getting trans serviced. hope this helps.

Well you can find out by un plugging the connecters one by one till you find the bad one (you have to plug them back in too. The bad coil will not change the running of the engine or go to autozone.com

I have a 1988 Honda Accord with about 137K on it.  It runs wonderfully.  Everything that you've replaced, I have also.  I also had to have my radiator replaced because the guy that owned it before me poured straight water into it instead of a water/coolant mixture, and water in Las Vegas is very hard, so the minerals built up and clogged it.  I would also check your water pump once in a while because I had to replace that as well.  In addition to visual inspection, I would feel all of the belts with my hands just to make sure that they still have teeth on them so that they don't slip off.  The spark plugs were something I had the biggest problem with, but those are easy to replace.

I would ask the engine manufacturer. If they are not available for some reason, I would look at current manufacturers of similar engines and see if you could adapt something. If this is an engine that has been used in cars or trucks, look for one in a junkyard. \n\nIt would help if you said something about what kind of engine, pump, and service this is in. Is is industrial? Agricultural? Some kind of experiment?

Possible that it is the cat. Save dollars and punch it out b4 replacing it.\nTiming may be out. Check this first. And not just at one mechanic.\nDid you replace the fuel filter(s)? Air filter?\nJust for an experiment, get some carb cleaner and while the engine s running, spray it around the intake manifold, base of the carb, any hoses you may see. If the engine starts to die or rev up, then you have a vacuum leak.\n\nGood luck.

It's a gasket - prevention of leaks.  Look into the Challenger explosion.  They had an issue with faulty O-rings.

from the factory most of the time the code is 1234,or 12345 but if you or someone has changed it good luck. If you have the manual that came with it it should be in there.As a last resort you might be able to take it to the store and have it reset.

If the 20A fuse is the size that is designed for the machine, then something is wrong with the machine.\n\nMost likely, either accumulated dirt, or worn out parts, or both, are causing the load on the motor to be much higher than designed. If you continue to operate the compressor in this way you will burn out the motor. I looked a little bit for on-line info about the compressor you mentioned but could not find it. If it is old, and replacement parts are not available, you may need to replace the compressor.\n\nOne possible transient cause could be a much lower than normal supply voltage - a brownout. If this is happening, the motor will draw more current and possibly blow the fuse. If this is the problem, the solution is to correct the power supply (if it is under your control) or to wait until it is normal again (if it is a utility supply).

Its on the lift cylinder. Some are just a rubber plug.

Incorrect valve clearances can cause valve to piston interference, cause excess cam and tappet wear and broken valve train components.  Incorrect timing can cause drive-ability issues, spark knock, or even burnt valves rough idle or a no start condition.

Been down this road with an 82 Transam that had crossfire injection.\n\nMy recommendation for you is to replace the intake manifold and install a holley 4 barrel.\n\nIn the end you'll save alot of time and effort.

what year chevy  it may not be much considering its only a 4.3 liter.  are you running heads and cam   what size cam?  Ported heads?   what type bolt on?  and what kind of car is it.  Are you looking at high or low end torque?   You may want to get a dyno pull

I thought it was 4 to 1, but better check your manual ,or the website, they would have more specific info.  Also, the fuel to oil ratio could be pretty generic for that type of engine, so even if you lost your maunual, find the stats for a similar engine and you should be safe.\n\nEdit: lol, better listen to the below poster, 4:1 and 50:1 is a pretty big difference, and I don't want you to send me your repair bill ; )
