SOURCE: rising and falling idle

Hey, first i would check all of your vacuum hoses. Over time they can crack and leak and that can create the problem, then the computer compensates to correct it. The throttle position sensor could also be a possibility and in combination with a vac leak, can create a wide variety of symptoms that are difficult to separate and trace down. Get a can of carb cleaner with the little spray straw, start the engine and let it idle to warm up. Spray a little on each vac connector, around the base of each injector or the throttle body, and see if the rpms run up. If so, you may have found a leak that needs tightening down. Vacuum hoses can sometimes just have the split end cut off and reconnected. The hard plastic spaghetti lines may be so brittle they need to be completely replaced. Manifold and throttle body bolts can be tightened up, but occasionally the gasket may need replacing. I would start with that and see what it does for you. Let me know if I can be of any more assistance.

My 93 honda prelude dont start i did a full overhaul but i can get it to start timing is right so i dont know wat to do next

Timing is right, but the firing order is incorrect then it could not start. Make sure connection at the spark plug is in the firing order. Let get back to the basic: need spark and fuel. After several cranking, take plug # 1 out to see if it wet. If it is wet then you have fuel. If it is dry then you don't have fuel. Start to find out what is the root cause for fuel not coming. Now touch the spark plug to the engine chassis and have a helper to start engine. If there is spark strong then you have spark. If no spark then you know what to do: find the root cause of the problem. If you have spark and fuel then need to recheck timing by Top Dead Center: Piston #1 is up, mark at camshaft and 0 mark at crankshaft all line up together while intake and exhaust valve closed. Good luck.

My 1993 honda prelude was recently stolen, and it has some issues


hummm, lets see here. you had plug wires stolen and you put new ones back on the vehicle. sounds like you may have gotten the firing order out of place. for a 4cyl the firing order will be 1-3-4-2. so as you look at the distrubutor, # 1 cyl should be going to the plug closest to the drive belts. and then 2 next and so on....

the way to tell where #1 cyl on distrubutor is.. "bump" over the starter until you see a white mark on the belt pulley line up with the marker on the timing belt cover. when you get that done. remove the distrubutor cap and look at which plug wire i's pointing to... it should be #1.... if not you have a firing order problem, (check all other wire orders... ) start with that plug wire being # one and then next (don't remember which way this engine goes clockwise or counter clockwise) but make sure the next in line is 3, and then 4, and then 2..... got it? ...... good luck and hope this helped.
