Why does your engine idle high in Park and Neutral but seems to be O.K. in Drive?
This is almost always caused by the Idle Control Valve (IAC), which is located near the firewall, on the passenger side, next to the throttle body. They sell for about $50. On generation 1 cars (1993 to 1996) these are very difficult to remove and install, but it can be done-or you could try to 'SEAFOAM" the intake by running a bottle in the gas tank and taking another bottle and run it through the intake by disconnecting the PVC hose while the engine is running, push the hose (it will suck the Seafoam into the intake) and then let it sit for about 10 minutes. Two bottles will run you about $14. When you start it up, expect alot of smoke-it might even bring the volunteer fire company, but it is the carbon build up being cleaned out of the engine. The engine should be fully warmed up before you do this. After you do this, disconnect the positive battery cable for about 10 minutes-it allows the computer (ECU) to 'relearn' inputs from the various sensors like the IAC. I actually did this on two Generation One marks I have owned, and in both cases, it cured the problem. The high idle in drive and park is tough on the engine and murder (in drive) on the already fragile transmission, not to mention the brutal effect it has on U-joints when you shift into drive at high RPM's, so you want to get it fixed as soon as possible or park it until you can solve it.
Drive cycle 1 Start (car should be warmed up already) All electrical stuff off. Assure all diagnostic jumpers are off. Idle (in park or neutral) Rev engine to 2500 rpm(1.5L) or 2000rpm (1.8L) for at least 15sec.(in park or neutral) Rev engine to 4000 rpm for at least 15 sec.(in park or neutral) Idle for at least 20 sec. Done Drive cycle 2 Idle for 3 min. Accelerate to 55mph in 5th or D for…
1995 winnebago vectra with Chevy 454 engine equipped with Auto Park feature The auto park feature is locked and can't get it to release?
Could be that your motor has a rev limiter. Does it only do it in park or neutral? My grand prix has a rev limiter of 3000 rpms. It seems like the motor starts stuttering like you are hitting the gas an letting of repeatedly. This should only happen in park or neutral though. Could be worth taking a look at though.
You can pop the linkage off at the transmission with a large screwdriver. This will allow you to operate the transmission shift selector on the transmission from park, neutral, drive and so on. The truck still has to be in park or neutral to start the engine. Chock the wheels and apply the parking brake and have someone in the drivers seat holding the brakes on while you're under there. You could easily be run…
Answer It's not really good for it...But make sure the transmission is in neutral and check the Transmission fluid to make sure it's full. It is essential that the shifit into neutral is immediatly preceded by placing the transmission into "Drive". Shifting from Park-to-Reverse-to-Neutral DOES NOT place the hydraulic switching to a towable configuration. Shifting from Drive to Neutral does. Put the ignition switch to "Accessories" position to free the steering wheel lock. Honda recommends…
Does it shift out of Park? If not check stop light fuse - shift interlock and stop lights are a common circuit If it does shift out of Park then shift linkage may need adjustment Try turning key to first position (Unlock) without engine running and the shift to neutral to start vehicle and then shift to Drive
Do you check the automatic transmission fluid in a 96 Toyota tacoma with the engine on of off in neutral or park?
More detail req Do you mean the engine will only run in park or neutral or the engine will only turn over and start in park and neutral? it sounds like the neutral safety switch is bad or out of adjustment. If they use one and I dont know the location if that is the case. Because there is an electrical short within the neutral safety switch that is interrupting the ignition. When you're in…
How do you change a 2000 Ford countour rev limit while in park or neutral Limit is about 3900 to 4000 in neutral or park But the actual car's top end is about 6000 RPM?
What could be wrong if a 1994 ford explorer xlt dies at random times and i have to put it in neutral to restart it again?
1998 ford explorer when you are in park or neutral it starts fine but as soon as you shift to reverse or drive the engine cuts off what causes this?
The engine of my 1993 Voyager 2.5 Liter dies at wide open throttle. It idles rough. Already did a tune-up and replaced the fuel filter. Seems like it is fuel starved for higher RPMs. Any suggestion?
If the engine seems to die at wide open throttle when the transmission is in park or neutral, that would be the rev limiter kicking in. If the engine dies at wide open throttle while in drive, I would suspect a damaged/plugged catalytic converter. A vacuum test could verify that. If the vacuum drops off as you increase rpm, you have a restriction in the exhaust system, probably the cat.
