Hi! Have you replaced the MAF (mass air flow) sensor? The MAF has big contribution on the engine performance specially the idle and vacuum supply. The MAF may be faulty thats why it runs rough when in idle. You will need to have it replaced. Hope this helps and thank you for using FixYa!

I have a 2007 jeep patriot. It stalled at stop sign started ran rough. Parked came back drove it home ran u- scan code p0017 replaced crank and cam sensors still runs rough changed plugs were bad. I was...


code p0017 refers to crank/ cam oosition sensor bank 1 sensor B -correlation ===causes --wiring--CKP sensor--CMP sensor--mechanical fault.
It also refers to control modules, cooling fan--no signal===causes -- wiring--ECM.
If it has a timing chain then the the advice that it will not be the chain is good. So I suggest checking out the cam/ crank sensors and wiring

I have a 2000 vw jetta glx with the vr6 that needs the timing chain replaced there is an upper and lower one. So I was hoping at minimum that someone could post a link to a complete walkthrough along with...


The Jetta vr6 has a timing chain. These don't have to be replaced unless the gear is worn. When worn they will jump timing by a tooth or two. This will cause the engine to run rough.

The timing gear tensioner on my stype jaguar 2001 was replaced after the chain guides broke...a common failure for that year with plastic tensioners...would it not be a normal procedure to check or replace...


Failure to change your oil every 4,000 at most,
takes out VVT Actuators

When you do the guides you do the tensioners
Again no oil flow & gunked up

You can see the VVT on scan tool parameters & also
should mess with fuel trim data

If you change the upstream O2 Sensors at 100,000,
spark plugs every 3 years & clean the MAF you at least
have a clean start, with the exception of the cam & chain issues

I install a timing chain on a intrepid 2.7 and it backfires what did I do wrong


that engine is an interference engine and you turned the motor with out turning the cam with the chain removed and possibly bent some valves or the timing is off 180 degrees

Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Code p0019 p0018 p0008


P0019: Cam/Crankshaft Pos. Correlation Sensor B - Bank 2
P0018: Cam/Crankshaft Pos. Correlation Sensor A - Bank 2
P0008: Engine Position System Performance (Bank 1)

P0019 & P0018
- Dirty Oil
- Engine mechanical problems
- Timing belt jumped teeth

P0008
- Engine mechanical problems
- Incorrect timing chain
- Stretched timing chain
- Failed camshaft actuator or actuator solenoid

The Engine Control Module (ECM) monitors the position of both camshafts and the crankshaft. The ECM performs a test for misalignment between both camshafts on one bank of the engine and the crankshaft. During the test the ECM learns the position of the camshafts and the crankshaft. While the engine is idling, the ECM compares the position of both the camshafts and the crankshaft with the learned value. The ECM will set the P0008 code if both learned values for one bank of the engine are exceeding a calibrated threshold in the same direction.

I have a 2005 F150 w/ 5.4. The following doces are reading on a scan: P0012, P0021, P0345, P0349, P0307. I do have a miss at times and rough idel. Any help would be appreciated


P0012 says the cam shaft signal is over retarded on bank 1, P0021 says that the cam shaft timing on bank 2 is over advanced. P0345 and P0349 means your cam shaft sensor cannot be read. Finally cylinder 7 (P0307) has a misfire. Changing your camshaft sensor would be a good start and then have the codes cleared. Switching the car on and off 5 times or disconnecting the battery negative terminal for 10 minutes will often clear the codes. With any luck everything will be resolved by the new cam shaft sensor. If the misfire is still present remove the spark plug and inspect it. If the plug is OK check out the HT lead and connection to see if there are any shorts.

One and only solution you will need to do a OBD2 Scan to retrieve the vehicle computer errors your guess is good as mine what it could be this scan will pin point the exact problem.If you haven't the scan diagnostics tool most garages charge $25-$75.00 for this service

1994 Cadillac DeVille Concourse - Runs rough?


The "check engine" light will "light" when there is a malfunction in the engine management system. The fault code is then stored in the computer. The computer must be scanned to retrieve these stored faults to pinpoint the malfunctioning component. We recommend buying your own scanner and doing it yourself. With a pocket scanner you can check for fault codes to find out why the light came on in the first place. You can clear your cars trouble codes after you replace the malfunctioning sensors.
