FIAT PUNTO punto P0300 Fault code

hi my punto started devoloping a misfire again i took it to my local garage and they ran a system scan. they found it said ignition failure p0300 i had a look around and couldnt find any proper info. what does this code mean is wrong my mechanic tells me it is likely to be coil or ECU as these are very common on fiat 1.2 8v (60).

Could well be the ECU . random misfire. Try swapping the leads to the coils over after having determined which cylinders are misfiring. (infra red thermometer maybe). If the cylinders dont change itll be that horrible pesky micro ECU . They can be repaired whichis one hell of a lot cheaper than getting a new one. Lots of posts here and something in either the guides or faqs.

its a generic code change plugs and leads before anything else

Had a misfire recently. No 1 plug had lost half its insulator into the cylinder. Made a nice mess of the head and piston crown after a few loud clicks on startup. Bosch plugs only 6 months old. Might have been early sign of HG going as well last one was done 26000 miles ago.

For me this was bad leads. Check those and plugs before coil packs and ecu . Also dont leave it to long it cost me a new cat.

FIAT PUNTO Dredded P0300 after timing belt change

My punto 1.2 8v 53 plate was running fine however mileage had gone over 60k so thought I would be proactive and get it replaced at my local garage. They changed it and all was fine until I hit around 76-80MPH then the ECU light flashes sometimes for 30 seconds sometimes for about 10 seconds then goes off. On one ocasion it came on and stayed on took it back to garage they reported p0300 code multiple

Needs the ECU self adaptive parameters resetting and Phonic wheel learn procedure performing. (Dealer job unless the local garages software is upto it) httpwww.fiatforum.compunto23219...und-70mph.html Local garages may be cheaper but if theyd called the local Dealer (or searched on here) theyd have had the answer Im giving you in seconds and saved themselves the time and hassle of replacing working plugs and leads and rechecking the belt.

FIAT PUNTO ECU fault - P0300

Hi I was experincing an engine light symbol displayed upon the dashboard whenever i went above 65mph. So i took it to fiat dealership and the computer reported an Error - p0300 which is a ignition failure(generic) intermittent with the danger of catalyser overheating. Has anybody else experinced this problem and what caused it The mechanic 90% belives its the HT leads Was this the problem for anybody

Ok the error is detected because the engine ecu sees a misfire due to the fact that the phonic wheel pattern has changed when the cam belt was changed. The phonic wheel is on the crankshaft pulley and is removed during the cam belt change because it never goes back in EXACTLY the same place the pattern obtained by the rpm sensor does not match the one stored in the ecu and at higher revs a misfire

Thanks Numan that sounds alot more realistic then what the fiat mechanic told us. He said it was down to the new spark plugs fitted not cambelt and he said that the HT leads needed replacing as there werent working properly with the new spark plugs although after saying that he said he was only 90% sure it would fix it which made me begin to doubt him as hes suppose to work with these cars day in day out

Originally Posted by NumanR The car needs to go on examiner and have a reset of the engine ecu carried out and then a phonic wheel learn procedure carried out this will cure the problem. NumanR Hiya Just to clarify is this the same as disconnect the negative terminal for 20 mins to clear the ECU reconnect Having all sorts go wrong with my punto this winter shortly before I changed the wishbones the

doubt the battery is at fault however probs getting a new battery first wud be a good idea the radio cud be a fuse which i think is F39 in the drivers fuse box check that first to see if that cud be the source of the problem and yes finally the 1.2 8v does have a cat and is 60Bhp

FIAT PUNTO occasional misfire - P0300 & P0340

02 reg Mk 2 punto 1.2 8 valve 85000 miles starts & runs perfect except what feels like a brief misfire now and again. The engine misfires for maybe 30 seconds and the yellow engine light comes on. Sometimes the engine light flashes and then goes out again when the misfire stops sometimes it stays on (not flashing) for a day or two. This happened about once a week for the last month or so. The codes

Zero the ECU codes then check with the engine cold and again when hot. If the sensor is failing its likely to be worse with the engine hot. Also check the cable connector contacts are clean.

FIAT PUNTO Misfiring - P0300 P0302 P0303 P0304

Hi all Just looking for some confirmation from anyone who is a bit more technical than me. Last night my car starting misfiring when ticking over and missing when accelerating. I had noticed in the last couple of days once or twice it seemed juddery and last night it finally stayed constant. Anyway plugged in my basic fault code reader and it came out with p0300 P0302 P0303 P0304 related to misfiring.

Its a 2002 - 1.2 16v Sporting. Thanks Originally Posted by whitz whats the year and engine size Ash

are the holes easy to spot are we talking about a tear in the rubber thanks Originally Posted by dave pull leads out and my guess is one will have a hole in one of the ends that go onto a spark plug that spark can travel to all the other plugs and does some strange things with codes often comes up as multi cylinder miss fire when only one lead has the hole

FIAT PUNTO Engine Maintenance Light on..Car is Shaking

My cousin has a fiat punto 1.2 2001. When he starts his engine(engine maintenance light on)the car starts to shiver and when he tries taking off he must push the gas pedal very hard so the car can move. The exhaust also seems to be making strange noises. when he is driving the engine maintenance light starts to flash and then it goes back to stable again. He told me that this problem started after

Since hunting for more info on the p0300 code within Google I found this link back to my favourite fiat forum website (see below link) httpwww.fiatforum.compunto72577-ecu-fault-p0300.html NumanR returned this interesting post (below) as we underwent a Cam belt change last September (When we purchased it) but never took the car on the motorway until recently. Ok the error is detected because the engine
