There is probably a computer access to the right of your steering column and a mechanic has a device that will diagnose your issue, possibly a worn catalytic converter, a misfire or who knows.

95 taurus with re manufactured 3.0l engine from ford runs rich at idle fails emission test. no codes, new motor from ford has 750 miles since install. o2 sens have been replaced no change still no codes...


check fuel pressure/volume, injectors, engine temp sensor for computer to know what the engine temp is, map sensor, timing, throttle position sensor. what emission did it fail might help.

Engine knocking noise


I currently own a 2003 isuzu rodeo that i purchased new in 2003 i recently changed the oil and was driving and heard a loud knocking / banging noise . I immediately pulled over and shut it off ,popped the hood and checked the oil only to find out i had plenty of oil. i asked a mechanic he told me to replace the oil pump and i did , but it still makes the same noise. it only has 80,000 miles what else could be wrong?

Double check your timing. Make sure that your belt is tight, and not over tightened, make sure that any bolts the you took out are put back in correctly. Those would be your only issues that I could think of.

I have 2003 grand cherokee with 140000 miles that overheats at idle. as soon as i start moving again, the temp goes back to normal.


You have two fan's on your truck, 1 is a fan clutch runs with the drive belt, 2 elec fan motor, with test light and engine running at normal temp, just a little bit above 1/2 way on your temp gauge check voltage at elec. cooling fan harness if you have voltage at one of the two wire's and fan don't turn on, bad cooling fan motor, on the fan clutch after you check voltage at elec. fan motor turn engine off, with your hand spin drive belt fan if it spin's freely bad fan clutch, replace it.Also check cooling level.Hope this was very helpful

My 1995 neon has ~105K miles, just passed emmissions with flying colors 1 week ago, and the ''check engine light'' came on. I have checked oil, coolant, brake juice, fan belt and air conditioner belt. Car...


the light has nothing to do with oil or coolant levels. it comes on for one of the following reasons. You will need to have the system computer memory tested to see which fault the system has.
CODE Description of Trouble Code
11 Timing belt skipped 1 tooth or more from initial learned value, Intermittent loss of either camshaft or crankshaft position sensor, No crank reference signal detected during engine cranking
12 Direct battery input to PCM was disconnected within the last 50 key-on cycles (normal)
13 No change in MAP from start to run
14 MAP sensor voltage too low
15 No vehicle speed sensor signal
17 Closed loop temp not reached or engine cold too long
21 02s sensor problem (oxygen sensor), upstream or down stream
22 Engine coolant temp sensor out of range
23 Intake air temp sensor out of range
24 Throttle Position sensor out of range
25 Idle air control motor circuits, target idle not reached (+/- 200),vacuum leak found
27 Injector control circuit
31 Evap purge flow monitor failure or evap solenoid circuit
32 EGR system failure
33 A/C clutch relay circuit
34 Speed control Solenoid circuits
35 Rad Fan control relay circuit
37 Torque converter clutch solenoid CKT or park/neutral switch failure
41 Generator field not switching properly
42 Fuel pump relay control ckt, Auto shutdown relay control ckt, No ASD relay output voltage at PCM, Fuel level sending unit volts out of range, Fuel level unit No change over miles
43 Multiple/ single cylinder misfire
44 Battery temp sensor volts out of range
46 Charging system voltage too low
51 Fuel system lean
52 Fuel system rich
53 Internal control failure
54 No Cam signal at PCM
55 End of error messages (If you get this only, no errors were found)
62 PCM failure SRI mile not stored
63 PCM Failure EEPROM write denied
64 Catalytic Converter Efficiency Failure
65 Power steering switch failure

Cold idle stays on too long


Has it always behaved the same? It has sensors that detect engine temp, outside temp, humidity and altitude to give you the perfect fuel air mixture for the conditions. 1300 to 1500 rpm is not unusual for cold engine warm up. You could have a bad sensor, but the codes should have revealed that problem. 10 minute warm up is not outside the norm. at idle, but 7 miles driving should make it happen a little sooner. As for the the stick moving when you "get on it", that is normal engine "torque", your engine mounts give just a bit to allow movement and to keep that "torque" from being transferred to the body/framework of the vehicle. You have hard rubber mounts. As they "fatigue" you will notice this movement increasing slightly.

No/low oil pressure, high engine temp


I think you have a bad ground on your engine gages...but, more importantly, have your oil pressure checked by a mechanic.  If it is indeed only 20 pounds the engine is sadly on it's last legs.
When you receive advice from this website you have to understand that without the item in front of us, we are only able to provide "a best guess" as to what the problem might be based on you description of the defect.  If you haven't described a clear and precise description of the defect you decrease the chances of an accurate reply.  Thank you.
