hi guys car is 2001 legnum 130thou km auto im fairly new here and having some trouble with a legnum i bought recently. driving home at night the lights turned themselves of for about 10 seconds and then came back on, did not think much of it at the time. following day car was running fine then my wife let the battery die by leaving some stuff on in the car so we charged it up and car was all good for about 30 mins then its stated to stutter down low and stall. would not start for abit but eventually came good. now the problem persists it drives fine for bout 30 mins then when you turn the car off and come back to it it will want to stall when applying pressure to the accelerator, you have to put your foot down to try and overcome the stutter and stalling to get it moving but that only sometimes works, usually it comes ok once you get it going but can also stutter abit when driving. the rear window has also just started playing up when you pur it up it gets half way then goes back down...... i have had the fuel pressure checked (think thats what it was) and seems fine the only think i can think of is maybe the ecu is faulty? no lights come on during these issues and has also been plugged into a scanner with no fault codes coming up. i am not exactly knowledgeable with cars but my dad is an auto electrician but he is fairly busy most days so its hard for him to get time to look at it, and help in the issue would be good, i hope all this makes some sense haha, thanks i could possibly get a video of the issue up at some point if that would be helpful. I will also just add that when the car comes good after its been stuttering and stalling it will drop 2-300r and once it's done that it runs perfect. It drops 2-300r when I leave it sitting there just idling and that's when I know that it is good to drive.
