When a engine is cold the revs should be higher ( choke on ) but nit going up and down. If you release the accelerator and the engine still rev's up maybe the accelerator cables are not properly installed on the carbs. Also a air leak is possible. Check the cables and air leaks at manifold including the holes from manifold where vacuum gauges should insert when carb calibration is necessary. Those holes should have some caps on.

SOURCE: rebuilt carbs-starts and idles but wont rev up without choke on

sounds like the main jets are partly pluged, you must remve all brass jets and seats including needle jet and its slide soak in carb cleaner and blow out with compressed air only.. hold up to bright light to verify if all are clean. jim

SOURCE: carb or manifold or exhaust problem hellllppppppppp

You have an air leak on the intake side of the motor. Get new carb and carb manifold gaskets. Tighten the bolts down evenly in three stages. For the exhaust, try the link below. It is a high temp silicone sealer.

SOURCE: suzuki 1200 bandit 1997 running rough at low revs

i had a similar problem on a suzuki gs250t custom, my bike would not start some times and if did start, would run erratically, and cut out, this was after i changed the spark plugs, found out that the supplier gave me the incorrect graded plugs.

SOURCE: I need tuning specs for my 1982 suzuki gs 750.

You need to fix the fueling first - without fuel it won't run!
Your other problem sounds like an air leak - either the manifold or the carb. Check by spraying WD-40 or CRC at the manifold and carb join while the bike is running - if the revs change (either up or down) you have a leak.

Have it looked at by a dealer,iam not sure here but i think you have a vacumn leak like the feed pipe to the servo split but really you need a mechanic who works on these cars day in day out and they will go straight too the problem for you

My 1988 Daihatsu Feroza is having some issues changing gears. when i take my foot off the accelerator and press the clutch in, it revs up about a grands worth, instead of the revs going down. this happened...


The issue is one of over-fast idling. First thing is to check coolant level in the engine. Make sure that the coolant is at the 'max' in the reservoir (1:1 mix of water : antifreeze). Low coolant would preve nt the ECU from detecting the car is at operational temperature. When the car is cold the ECU extends injection times to keep the car running but when warmed up the injection times are again shortened to reduce engine speed at idle. Also at idle, the Idle air control valve (IAC) on the throttle opens to allow air to by-pass the closed throttle plate. Check that as the engine gets warm that the coolant hoses to the throttle body become warm (showing that no blockage is preventing coolant circulation). Check that IAC air passage is clear and that valve can open freely. If the IAC coolant hoses are blocked or the valve is jammed open this would account for the very high idle speed. If everything looks OK check the PCV hose from the valve cover to the throttle and make sure that there are no blockages in it.

Saab 9-5 need to give alittle throttle for cold engine start


the idle air control valve may be bad or just needs cleaned out. idle air control valve acts the same as a choke. if it is messing up it will cause engine not to run right.

94 tauras AT once warmed up trans will drop out gear at a stop


This is a common problem. You have a cracked forward clutch piston. Ford made this part out of aluminum. The replacements are steel. But you have to disassemble the transmission to install it. ( I know you said Rev too, In the AXODE trans, the forward clutch is on in 1st and reverse)

91 geo tracker -automatic -gear change trouble at cold startup.


Well, there are a number of questions that come to mind from a routine maintenance perspective.
Seeing that it is a 1991, has the transmission ever been serviced. A complete oil change out and filter replacement should be done every 50K miles or so.

Let me know how many miles you have and if you plan on keeping the vehicle.

The car rev's from 1500 to 2000 r p m's once warm up and down


I had the same problem in my 97 civic dx. Once the car warmed up it would rev up and down whenever the car was idling over and over again. To fix it I found out that the spring on the throttle body was sticky and by spraying it with lubricant (WD-40 or something similar) and working it into the spring until could stretch and contract freely, I never had the problem again.
