Hey guys, so i was going down the highway to U of I after a weekend at home and i pull off to get some food and the car dies, so i restart it and it wont hold an idle it just dies right away. Crank it and give it some gas and put it in gear and take off. Everytime i shift the RPMs just plummet as fast as they can to 0, and if i dont keep it in gear it dies. When i was able to start the car and give it gas, above 2000 RPM the engine made some harsh noises, like something was loose in the engine gettin thrown around. Its like a jumping bean or fast paced knocking (but not knocking) from the head/IM area of the engine....Eventually i had to get a tow home and now am waiting til the morning to check the car out. I was wondering if anyone had any ideas wat could be wrong? It seems to sound serious which i hope it is not...

No other problems are present nor were they before this..

 

I hope this isnt true about your car but, i heard on some 5.5 gen a bolt can come loose from the trottle plate and get sucked into the engine..

 

I'm guessing you have a crank position sensor that died on you. Any warning lights on the dash?

 

Thanks for the input...Well the CEL was on for the fuel sender unit before(havent fixed yet) so it is always on, i will read the codes later for more tho (gotta but the scanner first). Since i cant crank it up right now i cant tell u what lights are on when the cars on... could a crank position sensor gone bad cause it to make that noise too? I hope it is the CPS instead of something costlier..

 

Here are the codes i got.... 1706 P/N switch, 0462 Fuel sensor low input(old), 0011 and 0021 and then they come up again with a pd after them, what does that mean? Theyre for the IVT sensors. And then 0113 IAT sensor. Ive heard the IVT can be a costly repair.. i have no idea where to start from here i was hoping it was the Crank sensor but no code was thrown for it...Anyone have any ideas? TIA

 

The P0011 is a code for "Cam Position Sensor". P0021 has do do with your engine oil perhaps has gotten dirty and blocked the oil passage in the "Intake Variable Timing Solenoid" that allows advancement of the cam.If you have allowed the oil level to get to low it will allow the sludge to get pushed up into the engine. The passage way in the IVT has more than likely got some obstruction in the narrow passage, an oil change is required and possibly and engine flush to try and clear the system up. As for the Cam Sensor (first check with the deal to see if your Vin is in range for the recall), you may not have an issue with the cam sensor because of the blockage at the IVT (once cleaned up you may find you have no issue with the cam sensor.
P0113 it is the air intake temperature sensor again this is still relating to poor quality in the oil crank case, Something is telling me your oil level got or is low and most likely very dirty ... You could also order a bottle of "Auto-RX" from their web site which will greatly help in dissolving the crap that is currently in your engine oil. It really does work, but is expensive at 38.00 bucks a bottle.

 

P1706 problem is the neutral safety switch/clutch interlock. Basically, the switch on the clutch pedal is probably gone bad and needs to be replaced. This is the switch that lets the computer know that the car is in neutral allowing the car to start.

Looks like this would be the first thing to get corrected, and then work on the engine oil quality issues .. well at least that is my take on all the codes your throwing.

Thanks for the input, I think your right with this, I was overdue for a change, had been traveling alot and i had added oil before but i should haver added more by now so im sure its low, and its probably dirty also. So do you think i should just have it towed to the nearest shop and have them thoroughly flush the oil system? Oh and also i tested the crank and cam sensors and all tested good, which agrees with what you said about possibly not finding a problem with them in the end.

It still tries to crank, it just doesnt succeed, if the switch caused it to not start wouldnt it not even crank? And i reset the codes and it didnt come back, altho the car hasnt really started, other codes came back. It makes a weak whirring noise it barely even turns over when i try to start and i have a charged battery...weird.

 

Well as I suspected you have more than likely managed to push some real crud up into the upper parts of the engine and IVT probably has some of this wonderful crud stuck in the narrow passage way which caused the P0021 and because it is not working properly then caused the P0011 to go off, the next code you would have gotten most likely would have been P0300 for multi misfire. So you do have some serious gunk& gum to get cleaned up an engine flush or two followed by a couple frequent oil changes and filter changes should resolve those issues as one has triggered the other.

And yes in order to flush the engine internals you pretty much have to get the engine going, which if it's not the switch then I would say yes to the tow and have a mechanic resolve the no start.

 

yeah this is what i was thinking too... thanks again for the input
