Im having a problm with my rpm jumping around then the car dies
Fluctuating idle is usually one of two things: 1) Great big air leak (often the Fast Idle Thermo Valve), or 2) Low coolant. Start by checking the fluid level in the RAD with the car COLD. If that's OK, remove the air cleaner pipe amd cover the LOWER port in the throttle body with your fingers. Does the idle settle down? More detail about your car would help a lot. * When exactly this "jumping" occurs * Mileage * Transmission type * Car's history * Recent work preformed * Recently neglected maintenance items * etc.
Likewise. But definitely do the checks Tegger gave. My next candidate for the cause of the problem is the ignition coil. See Tegger's great site at the following link for more help with these, especially checking the igniter and coil: http://www.tegger.com/hondafaq/faq.html#startrun
It could be, but the the OP's description is hopelessly vague. Igniters usually fail outright, resulting in a stall, then a later restart. He hasn't got a tach unless he's got an Si or has installed one himself, so his description of the RPM jumping" might actually be "bucking". And if it's bucking, then it could be a whole pile of things from bad wires to a bad coil to who knows what else. How long does it jump/buck before it dies? We do not know. Does it happen hot, cold, or during warmup? We do not know. We're all guessing here until he comes up with a better description of the symptoms.
About four months ago, I bought a $200 '82 Civic parts car that ran. In fact, it would start up everytime but before it warmed to operating temperature, it would "buck" violently. The colder the weather, the worse the problem. My overall experience kept whispering, "vacuum advance, vacuum advance." Finally, I disconnected the hose to the advance, plugged it with a bolt and the car ran great! So much so, it is registered and a daily driver. It does have an issue... Low compression on #2 cylinder of 100 psi with the blow by to boot. I see a ring job in the not-so-far future as otherwise, this car is very dependable and even though it has a weak cylinder, it still has good power in spite of consuming a quart of oil every 300 miles. Sometimes, the solution is like a snake ready to strike... JT
