rpms are jumping up and down?

The most likely cause is that your clutch is slipping. Either because the mechanism isn't working properly (rare but possible) or the clutch is worn (very likely). Have you checked your transmission oil level? Low oil level could cause your symptoms.

SBC V8 is an interference engine. You likely dinged some valves and/or pushrods crooked.

Look at the fuel flow from the injectors with the engine running, shuld look like a fine cone shaped mist, a bad injector can stick open and flow a heavy stream of fuel. ... An incorrect fuel pump (hi pressure vs. low) could cause rich running, you should see approx.

Air Conditioning blows warm air when accelerating...??? At higher rpm's, if it is low on freon, the pressure will drop low enough to kick out and cycle fast. This will keep it from cooling.

Stumbled across a simply fix by accident: check your "performance mode". Goto Settings, then Performance Mode. It's the icon that looks like a speedometer. Mine had set itself to "High Performance" when it powered up, and that seems to have caused the battery burnout and giant icons.

You will gain higher boost round mid revs so like 3-5 x1000. Also with all of that there should be a solid gain of 15-25 hp. When life passes you by, downshift.

The metal housing, vents, pipes and other parts make clanging and banging noises as they heat up and cool down. This is normal and shouldn't indicate a problem.

Most likely you have a clogged (or failing) idle air control valve. Take it out, clean it, put it back… should solve the problem. There's a disconnect between the amount of air the computer thinks your engine is getting and the amount it's really getting, so it keeps trying to correct itself and almost dies/comes back.

If the brake rotor isn't glowing red or on fire then I would say all is well. They will definitely be too hot to touch after a spirited drive. You're slowing a nearly 1.5 ton object from high speeds over and over. Heat is a by product of friction generated by braking.

Your car may feel like it's refusing to change gears as it normally does, or the gear shifts aren't very smooth. Sometimes you can feel or hear a noticeable “clunk” or “thud” when the car shifts gears. You may also notice the car has difficultly getting up to speed.

If your car starts vibrating and making strange noises like grinding or high pitched whining, it's most likely that your transmission is suffering. If you notice that your car has trouble accelerating or moving at all but you hear the engine speed up or rev, you're experiencing the transmission gears slipping.

Your torque converter can make a variety of noises when it goes bad. You may first notice a whine, similar to a power-steering pump that is low on fluid. The stator within the assembly uses an overrun mechanism with a series of clutches that, when bad, can cause a rattling noise.

The first way this can happen is if the float in the carb stays stuck in the open possition when the bike isn't running. When this occurs fuel will flow until it overflows into the crankcase thus contaminating the oil.

Any number of things can cause poor acceleration . Bad gas, clogged fuel filter, Clogged air filter, Bad vacuum lines to the transmission. Dirt/water in the fuel injectors, Bad Spark, Trouble with the electronics. ... Check the gas cap and make sure it is secured.

If you rev your engine to high RPM on occasion and only keep it there for brief periods of time, generally this is not going to cause much damage to the engine. ... High RPM causes more wear on the engine components than lower revs. Every engine has a point where it will come apart internally at a certain speed.

While extremely low rpm and high loads will damage your transmission right away, sustained high rpm may damage it over the long run. High rpm means more wear on the bearings and oil seals, and quicker transmission fluid breakdown.

There isn't one, rpm is how fast your engine is spinning, MPH is your actual speed. low rpm in 5th gear can have you going over 100mph while high rpm in first you are probably going under 60.
