Your Throttle Body Sensor works to sense the position of the accelerator. It could be bad. It there has been recent work done on the car check to ensure that there are not any loose connections at the throttle body. If a lose connection is found unplug the batery for over 2 minutes. Fix the connection and then hook the batery back up. Best of luck.

    - Intake air leaks
    - Dirty mass air flow sensor

Need vacuum diagram for ford telstar v6 1983


well if u have a 1983 ford tarus that has made it this long congrats... start by cleaning the mass air flow meter with mass air flow cleaner anything else will damage the electronics inside.. if it has had all the basics checked ie: plugs cap rotor fuel pressure then consider the coolant temp sensor.. if it reads different then actual temp it can cause cars computer to send wrong amount of fuel to air ratio..

Saab 2006 1.9tid 150 acceleration problems to 2000 revs when turbo kicks in and accelerates well from then on recently had new EGR valve fitted fuel filter and fuel solenoid poor running at idle been told...


This is usually the first (cheapest) place to start. The MAF (mass air flow) meter is designed to sense and adjust the vehicle engine to changes in air temperature, speed, density etc. to keep your vehicle running properly. Since you already had your EGR replaced (yet another possible source of this sort of problem) I would tend to lean more toward the MAF. If you run any sort of aftermarket intake such as a k&n etc. these can cause problems for certain vehicles that are very sensitive to air flow as Saabs tend to be. Also the oil used on filter elements such as k&n can ruin the sensitive MAF. This unit is generally easy to fix (it's the little box with wires running to it) mid way up your air intake tube just past the filter. They aren't too terribly expensive either. Try this and hopefully this gets you up and running.

Idle and Power Where is the fuel filter?


Fuel filter is inside the gas tank and its built into the fuel pump housing. You need to remove the back seat and get into the tank via access hole under the seat. Than you need to "split" the fuel pump assembly open and get the filter out. Reverse procedure to assemble. Those filters are rated for 105k miles. My 00 Maxima has 167K on it and it runs just fine with the original. As far as the air flow meter , its a pretty common part that fails and that's why 00 Max air flow meter costs only $100 and all others $500 or more. If you replace an air flow meter, make sure that you use a "NISSAN" air filter or YOU WILL BE replacing the air flow meter AGAIN. Also with the new air flow meter the cars ECM/Computer needs to be reprogrammed. As far as plenum gaskets leaking?? unless someone had it apart and didnt put it back together the right way, its "VERY UNLIKELY" for those gaskets to be bad. Totally bullet proof.
