Strep 1 is to read the CEL code.

Please dont make two identical threads. :c

I do agree with HiFlite, get the code read ASAP.

sorry im new to forums thought it never posted i will get the codes done just hoping its not a new engine that is required

Shadow0364

the coil pack was replaced 2 years ago could that be the problem

Cliffjumper126

it could be that and 15 other things as well. Get the code read before doing anything else

Shadow0364

getting the code done tomorrow it sounds like there are nails in my engine

Slidin8

Sounds like new engine time

Shadow0364

praying its not lol i never paid much but its a great car would the codes tell me if its low compression

Slidin8

No only a "Rotary Engine" compression tester can tell you if it's low compression.

No point praying, hearing "nails" inside your engine generally means you've blown a seal.

how would i know if its the cat does a clogged cat sound the same

Slidin8

Take it off and have a look at it. No it won't sound the same.

You said the nail noise is coming from inside your engine, not your exhaust system.

Shadow0364

its hard to explain i heard a bang and since then at low rpm its dies but it shakes as well its like a clanging noise

Slidin8

I recommend a compression test anyway

Shadow0364

i will do i only paid 600 for it few weeks back so was expecting something

Slidin8

Expect it to cost you at least 3600 now

Shadow0364

i will just sell it then i went one youtube and comparing sounds its like a gone spark plug but would that cause it to die at low rmp and shake thats for the help btw

Cliffjumper126

a bad spark plug would not cause "banging" or "nails in your engine". Just get the compression test and go from there

zoom44

you are having an ignition problem that includes ping/knock and the inability of the engine to idle or make power at low revs. thats more than likely bad coils but could include bad/fowled plugs and up to blown engine. a further diagnosis will determine which

update

i changed one coil pack and it was sitting just below 1000rpm for a good few min rev a bit then it died also one of the spark plugs are rusted at the end where you plug the lead into and noticed the spark plugs was last done 2011 and only coil 4 has ever been replace done a ohms test all passed fine on a-b but none gave a reading on b-c.could i need new coils and spark plugs when it was running the higher the revs the more the gear stick shaked

zoom44

I'm sorry, is there a question in there?

Shadow0364

I got the codes done this is what came back P0103 P0113 and P0302 only noise is no a rattle seems like it's around the cat

Shadow0364

Any help please

clean your MAF and IAT. clean out the intake tube check the air filter and either clean it or replace it. clean out the air box if its still in place. is this stock intake?

Shadow0364

I cleaned out the intake tube found oil yes it's all stock changing spark plugs tomorrow
