Have you replaced the fuel in the tank? If your car has been sitting that long with an old tank of gas the gas won't ignite, it loses it's volatility. Try draining the fuel that's in there and replacing it with a fresh tank. You may need to drain and replace the fuel filter too before putting the new gas in there. You need to get the old gas out of all the lines too, so it may take a while to start but once the new fuel is in there it should go. Let me know how it goes!

SOURCE: 1990 porache 944 cabbriolet

The top on my '91 S2 cabriolet also wouldn't open when i bought it about three years ago. the electrician tested the motor and it was working with direct power. turned out it was the relay that prevents the top from retracting when the car is running. We didn't find where the relay was located but we ran a bypass and added a secondary relay to the bypass located behind the tray under the radio. now ist good as new as new. before u do that though,m try lifting the top's lip while pressing the switching, that can keep the motor from starting as well. good luck.

ok, your problem is your fuel. your carborator cannot sit that long with fuel in it. try getting a can of carb cleaner and spray it while its running, or have a mechanich clean it if you don't know how.

Here are some things to look for. Also is your car shooting any check engine (ODB) codes? Alot of times if you are running a catless exhaust and dont have MIL eliminators it will shoot a check engine code but then again I've seen mustangs that dont shoot the code.

-Check for vacuum leaks your system can detects a leak as small as 1mm in size. Yes this even means check the security of your oil cap. check all hoses that attach to the intake manifold and all hoses that run downstream the MAF and upstream of the 02 sensors.

-Clean the MAF, that helps alot. I just took it off and sprayed some brake cleaner all over it and some on the sensor itself and repeated it about three times.

-Take your CAI off to get to the throttle body and inspect it and then manually open it and see how much black residue or how much dirt is on it and you can take some electronics cleaner and spray it down but dont scrub hard the TB's have a special coating on them that you dont want to take off but be sure to get everything cleaned evenly.

-I also had an 02 sensor go bad and that took some power away from me as well.

-Also it can be a clogged or bad fuel filter as well. You could also running some fuel system cleaner through your car. I remember it helped my friends mustang out.

-Sometimes it can be a buildup around the throttle plate, try hitting the throttle inside and out with carb cleaner.

Abs problems i have a 98 k1500 the front right

Inspect the ABS sensor on the front wheels, make sure that there is no damage to the wire leads and that the ABS sensor is not damaged or touching the speed ring on the front wheel hub. You may be luck and the ABS sensor is dirty, it can be cleaned with a good spray of brake parts cleaner and make sure the ABS is not loose from the mounting bracket on the hub. Good luck and keep me posted.

My 2007 CRV fuel efficiency has dropped more than 40%

invest in a tin of good quality brake cleaner open engine bay remove each multiplug on engine and gearbox one by one and sparay with brake cleaner do this one at a time (brake cleaner evaporates and doesnt do any harm) it is most likey to be a bad contact on the map sensor(manifold pressure sensor) or the ecu control valve DO NOT USE ANY ABRASIVES TO CLEAN THESE as this will destroy the plug and they are very sensitive could be an oxygen sensor but unlikely

Low rpm on start up, check engine light came on.

If you dont have a code reader go to Autozone and have them read them for you. it sounds as if you may have a defective sensor. It may be a simple cheep solution to try to clean your mass air flow sensor. You Can do this by taking some brake parts spray cleaner to clean it up. the brake parts cleaner dosent leave any residue so it wont harm the sensor. If you dont know where the sensor is located it is usually located just after the air filter box.
