hi i am not 100% sure but i think it is the P11 144 gearbox its used with the almera qg15de engine. i think it is also used in a primera and almera tino of the same years.

I have a 96 pantera 580 efi that will run but only while playing with the throttle it will not idle on it's own any ideas


Sure!

Fuel Injection systems are actually pretty bullet-proof.

The first thing I think when I hear "efi".... is AIR MASS VALVE (throttle body) or COLD START VALVE (extra FUEL source.. choke equivalent)... because I have had it handed to me a couple of times by exotic cars.

Despite my brain working in such an odd fashion... most of the troubles resolve to ordinary causes...

Won't idle is a very specific and narrow area
It gives your injectors, filter, exhaust, spark and fuel pressure a probable clearance... that is putting your cold-start circuit and ecu in the line of logic.

BEFORE we get all exotic about fuel injection we need to consider this is a "SEASONAL" vehicle...

Cheapest first course... dump the fuel and refresh with clean fuel (include a wee bit of injector cleaner)...

Before going out to buy that spare ECU (efi control board)... you always wanted (any way)...

If you plan on keeping your Pantera... good spares are always good to have!

Good hunting and good luck

I just bought a 2000 cavalier and the check engine light is on as well as the track off and abs, and when I checked the oil smoke was coming out the dip stick hole and after I let it idle for 30...


From you description I am thinking that the motor needs a rebuild . Smoke out of the dip stick hole is an indication of fire in the sump burning on hot oil gases. The fire is from compression and ignition by-passing the rings into the sump. The idle and resulting smoke is from failed valve stem seals and oil by passing the oil ring into the combustion chamber. The engine light is probably from the O sensors failing to control the ECM. The best check of this is to have a compression test done on the engine to check the internal condition

My 1997 Plymouth Voyeger will not pass a smog check. Computer keeps resetting itself. The visual inspection passes, and the emissions test passes, but the functional check fails. The inspection station...


I am only guessing but it seems to me an ECU that can't remember anything is probably faulty.

Inside the ECU or ECM, the brain, the computer can be divided into sections like the circuit board of a radio or a laptop. There will be voltage regulators, an obd interface, a memory for the fault codes and a memory for recent history and a memory for the learned settings. There will be a memory for the preprogrammed settings and drivers for the ignition and injection system and an active computer making sense of the sensor information in order to make constant adjustments.

Just as with most things built on a single circuit board they rarely fail en masse. Usually what happens is just one of the on-board systems fail even though the result for practical purposes is the same as if the whole thing frazzled.
Usually When an ECU fails it is one of the essential functions which leaves no doubt it must be replaced but it isn't inconceivable that any section could fail - even one or more of the memory sections...

High idle after replacing idle air control valve


There should be a rubber o-ring around the base of the section of the iacv (the portion that fits inside the manifold). Make sure this is seated properly. If it is not you may be allowing air to pass. This would increase idle speed. Also make sure to check that the valve itself is properly seated and tightened into place. If no this may also allow air to pass unrestricted into the engine. Good Luck

I have changed everything: Spark plugs, Wires, Coil Packs, Ignition Control Module, Air Idle Control Valve, Throttle Position Sensor, Map Sensor, Cleaned out my PCV valve. My EGR Valve is in great shape so...


There are three components that will enrich the fuel mix: 1)engine coolant temperature sensor. If this is not working or the signal is interrupted by a wire breakage then the engine will run rich. The coolant sensor informs the ECU (high resistance) that the engine is cold at start up and so the ECU responds by increasing the fuel injection cycle to enrich the fuel air mix. Later on as the engine warms the resistance of the coolant sensor drops and the injection cycle is reduced by the ECU. If the sensor is faulty or has become disconnected (wire break or corrosion of the socket pins) the ECU assumes that the engine remains 'cold' and the engine runs permanently rich. 2) O2 sensor, operates completely independently of the EGR, if it is faulty and signals 'too much oxygen' then the ECU will significantly enrich the fuel mix to try and balance what it thinks is an excess of air. 3) Fuel pressure regulator. If the diaphragm has broken or there is a leak in the vacuum line this will result in higher than needed fuel pressure in the fuel rail at idle. The vacuum line acts against the spring pressure holding the valve closed. At idle, the inlet vacuum pulls back on the diaphragm reducing the fuel pressure required to open the valve. Low fuel pressure coupled with short duration injection times will mean a lean mix at idle. If the vacuum is compromised or the diaphragm damaged then the increase in rail pressure will make the fuel mix very rich to point of flooding the engine

Idle speed control


Hmmmmmm.... seems to me you have a completely different problem since you've verified the idle control valve is working. What controls the idle control valve?... AH!... the ECU!... is the wiring between the ECU and the Idle Control Valve in good condition and making good connections? mmmmmmmmm... then I'd say you have a defective computer (ECU). Here's something you might try. Disconnect the battery connection cables from the battery... touch them together (cables + & -) for thirty seconds. Reconnect the cables to the battery and see what happens. Sometimes there's 'GARBAGE' stored in the ECU memory and interferes with the normal operation of components. If nothing changes, you'll need to start testing (bench testing) components (idle speed control actuator (make sure it's not 'sticking'). check for vacuum leaks.... thoroughly inspect intake air hoses & vacuum hoses... inspect all EMS (Engine Management System) connectors for any signs of corrosion or mal-connections (male & female pins). The problem may simply be electrical contacts/connections.. .then again, it could be mechanical.

Won't idle after replacing battery, engine dies.


Hansandfranz is 1/2 correct; the car does need an "Idle Relearn", but, you do NOT need a scan tool for this. The vehicle just needs to be driven for the ECu to relearn the "base idle".
Get in, drive it down the highway. Do some passing gear downshifts. Pull off to the side of the road, let it idle for 30 seconds, repeat 2 more times. Then, try to duplicate some "in-town" (stop & go") driving, for about 15 minutes.
This will reset the "base idle", and your stalling condition will disappear. Expect to have to do this again if you replace the battery. Very common; the Computer (ECU) loses the base idle parameters when the battery is disconnected. Easily rectified just by driving as mentioned above. Feel free to comment back if you have any other questions.
