My car engine stops while the car is running, cannot start for about 15 minutes then it starts and runs fine. this is an itermitent problem that the mechanic cannot replicate and the diagnostic does not show any code. The dealer could not diagmostic the problem either suggest chaning the fuel pump. The fuel pump was changed at great expenses but the problem persist. do you have any suggestions?

I have a 2006 Suzuki Forenza. Last week the engine light started flashing and the engine started misfiring during exceleration, especially in low speeds (under 20mph). It appeared to run fine at firt at 35-50mph, but soon had the "shudders" then as well. A mechanic said it was giving a diagnostic code that showed cylinder 4 was not firing. I replaced all the spark plug cables and it appeared to run better. However, now it is starting to act like before except I have yet to get an engine light


You may have a trouble code without the check engine light, but normally the light comes on too.The code was probably 304 which means cylinder 4 is not producing power. That can be caused by no spark, no fuel, or no compression. ... 2006 Suzuki Forenza

My 2000 Jaguar s type 4.0 displayed a "Failsafe Engine Mode" after filling the tank. The car operates fine so I took it to a local repair shop and had them pull the ODBII codes with a Matco Pro handheld diagnostic reader. All systems cheked out and we got no codes. The shop suggested a throttle body clean and general fluid change and replinish. I have heard that a throttle body clean can damage the throttle body. Should I get it cleaned or not? What else could I do to correct the problem?


It means that a fault has been detected and stored by the engine management system. The fault most likely a component within the engine electrical system e.g a camshaft sensor, crank sensor, O2 sensor etc.The only way to narrow the fault ... 2000 Jaguar S-Type

Engine code 1759 on 2005 Nissan Pathfinder, I live in AZ and when it gets over 108 my car does not want to accelerate when I start from a stop. Today I had the transmission fluid checked and the fuel system cleaned and it worked great until it got really hot this afternoon and the service engine light came back on and it started doing the slow start again. Once the car hits 30-35 mph, it runs great until I have to stop again. They did a diagnostic test and it came back with a code of 1759 which


I also have a 2005 pathfinder. I just, today, got p1757 and p1759. I am having the same problem you described. I also noticed the tempature difference. I live miami, fl. I read something about front brake valve solenoid forcing the transmission into ... 2005 Nissan Pathfinder

1999 Porsche Boxster - The diganostics call checking the mass air sensor by connecting the diagnostic device and driving the car in 3rd gear to 35 and then pressing the gass pedal to the floor to raise to 5000 rpm. The car will not raise to that level to test the sensor. All other test are in normal range. Is there and alternate way of testing or other suggestions as to what I should do. The car runs well as long as I don't try to floor it. The codes indicate it is running very lean.


If you can check actual values whilst engine is idling, air mass should be around 18kg. The symptoms you mention indicate a maf sensor is at fault, these are prone to failing and can cost around £300 from porsche ... 1999 Porsche Boxster

My Pathfinder runs fine until it gets to about 30 MPH, then the engines starts running rough. The computer code says the problem is the catalytic converter. The car has about 76k miles. That seems to few miles to have to replace the catalytic converter. Any other suggestions?

1994 Jeep Grand Cherokee After disconecting the battery for recharging and reconnecting the battery the blower motor runs continuously. Went through the ATC diagnostics illustrated in the Haynes man. and it illustrated code 08 "feedback too high", Blower/Fan feedback circuit.

P1000 When engine is cold it will start and run with no problems. When engine is at desired run tempature it will start and run no problems. When engine is at mid tempature engine will misfire and run rough at idle when trying to start.If you don't rev up too 2000rpm's for a 1 or 2 minutes it will stall and then is very difficult to get started again. Ran diagnostics on it and it's showing code P1000 / "On Board Diagnostics"


P1000 is not exactly a trouble code, but rather a fact code that means the system has not been run long enough to get into a full test mode.There could be a problem with the computer, or something that is keeping the system from going into closed ... 2002 Mercury Sable
