take it back to your mechanic and have him check it again, he may have missed something, or it has more wrong with it than he found on that visit.

My car won't accelerate seems there is no pressure its Audi A4 2006


Most of the time when an epc light comes on and you have no throttle response it's best to connect it to a bag-com but if you don't have one have the computer scanned for a check engine code remember just because there's no check engine light on doesn't mean the ecu doesn't have on in memory.. So if you do have a code like p1639 then you have a bad accelerator peddle

Dose this mean computer die?wont start new fuelpump so where do i go from here ? new computer or what


Take it to a ASE certified repair facility ,they'll fix it up ! Don't just replace parts !!!!!

P0171 - is a lean code bank 1 -possible vacuum leak , low fuel pressure , plugged fuel filter ,
P0300 - is a random misfire code which is understandable with a lean code .
P0420 As the code description implies the P0420 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting). Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P0420 code is combined with other codes, try fixing the other codes first
P0452 - EVAP Control System Pressure Sensor Low Input
P0446 - Evaporative Emission Vent System Performance
P0453 - Fuel Tank Pressure Sensor Circuit High Voltage
P1639 - PCM 5 Volt Reference Voltage Circuit Condition
P1653 - Power Steering Output Circuit Malfunction
P1651 - Fan 1 Relay Control Circuit
If you don't know what your doing take it to a repair shop before you waste your money ! You have a lot of problems here an I don't think the computer is bad , I'd say lack of maintenance ! You need to learn how to test thing's to fix them ! From the five volt reference voltage code , I'd say one of your sensors is shorted internally bring down the ref. voltage circuit causing the no start, but then again the 5volt ref. circuit in the PCM could be the problem . What you need to do is Disconnect all sensors that receive 5volt ref. signal one at a time an see if it will start . If I knew what year vehicle yours is I could tell you what sensors ! MAP, TPS , etc...

Vehicle is slow accelerating, when stopped rpm idles low, vehicle begins to shake and sometimes either shut off or wont accelerate when pressure is applied to gas pedal. Truck burning ALOT of gas?????


This is more than likely the Mass Air Flow sensor. It is located in the large tube that runs from the air filter to the throttle body. If the check engine light is on, and it should be. Then take it to Autozone and they will pull the codes to find out exactly what is wrong, free of charge. More than likely it is the MAF sensor, but getting the codes will be sure. Also you can unplug the MAF sensor and see if it changes the way the engine runs. If so, then it is more than likely the MAF sensor. But it could be a bad Throttle Positioning sensor also. So getting the codes would help tremendously in diagnosing the problem.

Hello: If you will pull up the carpet behind the drivers seat next to the edge you will see wires going to a connector going through the floor, disconnect this connector under the truck. Remove any water and corrosion, make sure connector is tight and making good connection. You may have to go to auto zone or advance auto to clear the codes. They may not charge for this.

I would take it back to Autozone and have it rescanned now that you changed the fuel filter.
The fuel pressure regulator may be at fault off the top of my head.
Try some fuel injector cleaner, too, if you suspect a fuel injector is plugged up.

1999 ford expedition p0452 code .what to inspect or part to change,thanks


Code P0452 is usually caused from leaving your gas cap loose or refuelling the truck with the engine running. Sounds rediculous I know. disconnect the battery to clear the code and try to keep the cap tight or quit fueling with the engine running.

Check engine lite is on, power lost lite is on. code p1276comes up. replaced throttle body, but no change. volts at vac fuse 14 both sides. will not accelerate over 1800 rpm's. 2004 trailblazer with 6cyl.


Your CODE P1276 refer to the Acelerator Pedal Position, Sensor 1 Circuit Range Performance.

Probable cause: Wiring, APP or ECM


GM - P1271 Accelerator Pedal Position Sensor 1-2 Correlation

I also found this... though its for Trailblazers... but may give you a clue:
Reduced Engine Power Message and/or Check Engine Light with any Combination of the following DTCs: P0107 P0112 P0122 P0452 P1120 P1220 P1221 P1271 P1275 P1280 P1481 P1515 P1540 P1633 P1635 P1639 P1682 #PIP3192 - (Oct 18, 2004)

Reduced Engine Power Message and/or Check Engine Light with any Combination of the Following DTCs: P0107 P0112 P0122 P0452 P1120 P1220 P1221 P1271 P1275 P1280 P1481 P1515 P1540 P1633 P1635 P1639 P1682 PCM Repeat.

The following diagnosis might be helpful if the vehicle exhibits the symptom described in the PI.

Condition/Concern:
Reduced engine power message and/or check engine light with any combination of the following DTCs: P0107 P0112 P0122 P0452 P1120 P1220 P1221 P1271 P1275 P1280 P1481 P1515 P1540 P1633 P1635 P1639 P1682

Recommendation/Instructions:
If the SI diagnostics did not isolate a concern, the following information may be helpful:
- Inspect the main engine wiring harness between the PCM and the generator assembly for a potential short to ground. There is a metal wiring harness retainer in this area that secures the main engine harness. If the harness conduit is mispositioned, some of the wiring may become exposed and chaff on the harness retainer. This may eventually cause the exposed circuit to short to ground.

- Inspect the 3 harnesses that connect to the PCM for potential shorts to ground on the metal PCM mounting bracket, just below the PCM. There are plastic harness retainers on the PCM bracket that secure the harnesses to the PCM bracket. If the harness conduit is mispositioned, some of the wiring may become exposed and chaff on the PCM bracket. This may eventually cause the exposed circuit to short to ground.

- If a chaffed circuit is found in either of the above locations, repair the circuit using the necessary SI procedures. Once the circuit is repaired, tape the area of the affected area of the harness to prevent the wires from becoming exposed in the future and secure the harness using the original harness retainer.

This applies to 04:
- 4.2L 5.3L LL8 LM4 Engine with DTC - P2120 or P2122 or P2123 or P2125 or P2127 or P2128 - kw low MIL pedal power reduced #PI01746 - (Feb 17, 2004)
- 4.2L 5.3L LL8 LM4 Engine with DTC - P2120 or P2122 or P2123 or P2125 or P2127 or P2128.

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Condition/Concern:
MIL light on. Reduced Power message on DIC. Possibles DTCs P2120 and/or P2122, P2123, P2127, and P2128.

Recommendation/Instructions:
The APP harness is clipped to the accelerator pedal bracket. The harness may chaff on the upper portion of the accelerator pedal causing a short to ground. Verify the harness is not chaffing on the accelerator pedal. After repairing the short, reposition the harness to ensure no contact between the harness and the accelerator pedal.

Hope helpes.

Cuts off at 70mph when accelerating.


Best thing to do is go to an Auto Zone and have them scan your truck for any DTC codes. Auto Zone scan free of charge, there is just to many things that can cause the engine issues your running through such as detonation during acceleration due to timing issues to lack of fuel pressure. Good luck and keep me posted, be glad to help you get your truck running 100%
