Sounds like dirty injectors....Have you tried injector cleaner? Make sure it is the one that removes and not prevents corrosion. I believe STP has it in a silver bottle.
Hopefully someone can back me up on this

    How many miles? I do like the injector solution because you have followed the fuel trail and spark trail. Crazy thought pcv valve? pull it out shake it does it rattle. Might be a three dollar miricale.

I have a 1997 SAAB 2.0 Turbo and it has started to run rough after it warms up and when driving it loses power and runs very rough until power taken off. Any ideas?


suspect low fuel pressure to the injectors
run the fault codes to determine where the fault may be before you spend money

I have a 90 chev blazer that runs rough when i apply the brake ,it also has a high idle and runs rich .?


I would look at the vacuum booster control unit .
This is the power assiest for the brakes it runs off the main engine vacuum,
If its leaking inturnailly you would lose engine vacuum that would make it run rough when you hit the brakes .
Also if the check valve inside of this unit were stuck it could cause a vary high idle
Try hitting the brake pedel when its idleing high in park and see what effict it has on the engine speed .
If it changes this is for sure your problem.

Engine Misfiring. Rough Idling. Losing power going up hills. Engine light flickered one day. I brought it to dealer. They said cyl 5 had a fouled spark plug. They replaced it, retuned and cleared code....


It sounds like it could be a bad coil pack that is used for number 5 cylinder. It could also be a bad spark plug wire. Does the weather seem to make a difference? Try this quick check once night time comes around. Open the hood and start the engine. Fill a bug sprayer with salt water and spray the plug wire while the engine is running. If the wire is bad, you might notice an electrical arc from the wire to the engine block. The engine will probably start running rough. If this occurs, then the wire should be replaced. If it doesn't, then the coil pack can be tested with an ohm meter. I hope this information has been helpful to you. Good luck with your problem and thank you for using Fixya.com.

97 chev tahoe service engine light is on and it wont start


P0300 is random multiple misfire. If its been more then 3years since the last tune-up, do one. Usually it is caused by debris inside the distributor cap but could also be plugs wires, fuel and air filter.
