Default 2.0L Petrol 2001 with issues

I bought our 2nd PT recently, I knew it had some suspension problems, replaced Bell Crank and going to replace all suspension joints with Energy ones when they arrive. However I have a couple of engine problems also that I need some advice.

1: When accelerating hard at low revs (e.g. pulling away from lights) there is a rattle from the engine making sound like a diesel, on light acceleration or at higher revs and normal driving there seems to be no problem.

2: Standing still and gear in neutral hit the accelerator engine revs up, take foot off of pedal and revs die but very slowly.

Any suggestions?

Thanks in advance guys.

Tony

for all intents and purposes of this post it's a 2.4.

Number one sounds like detonation- Select a lower gear when accelerating or buy hi octane fuel.

The idle motor might be full of carbon

Thanks guys, it is a manual shift box and non turbo. As UpTownSport says consider it a 2.4 but without the power

As I say I get the noise from standing start from junctions etc, so choosing a lower gear is not an option and we only have one octane of fuel available in the UK. I don't want to words in your mouth but could this sound be pinging (I always thought the word was pinking!) from poor ignition due to bad plugs/leads. I had this years ago on another car but it did not sound the same.

Still not sure about the slow die down of revs either.

The 2.0 will blow the pants off 2.4s people put in
Neons- Chrysler rates HP exactly same.
Not the best choice for the PT tho, like a Ferrari engine in a dump truck!

See if you can download the Factory Service manual and go thru knock sensor tests. Ensure engine isn't running excessively hot.

Look for threads here on testing / cleaning IAC (Idle Air Controller)

Sorry to bump this guys but I am still in need of help. I have been reading up about the knock sensor and understand how it works and what it does, but if it were faulty would there not be a code stored? I have retrieved codes using the ignition key shuffle and the only one I get is the "removed battery" one.

Searching the internet I can not find a specific test for the sensor unless anyone has this. Usually people suggest measuring the resistance or tapping near the sensor with hammer and look for an AC output. Is this what you guys suggest?

Another forum, not PT, described the sound as a tin full of marbles when accelerating, that is a pretty accurate.

The only other thing I would add is that before I bought the car the previous owner had the timing belt changed, if this were 1 to 2 teeth out could this be a cause? What effect would you expect to see if the belt were not set correctly and is there an easy way to check?

Thanks guys

Tony

I've never dealt with one failing-

There's not a redundant device, so it really can't check itself to make a code.

IIRC, there's specific torque values for installing a new one.

You should check cam timing if in doubt.

Jass; I would pull the plugs and do a visual. They should all look the same.

EGR valve stuck? --- Intake leak? --- Carbon build-up in combustion chamber? --- PCV valve?

Think of all the possibilities. --- I'm still thinking about 'pinking' !
