My truck's developed a bit of an issue and I was wondering if anyone has had something similar before?
'95 K2500 5.7 TBI
It starts and runs just fine when its cold and it's ok when it's hot too. No problems. But if I stop and leave it parked for 30 mins or so and then fire it back up it has a misfire at idle, it will nearly die and then pick back up again. If you drive it then it intermittently feels like it has no power and then it will surge as it starts running right again. After a couple of minutes driving it clears up and runs perfectly again until you park up.
From a cold start it's fine.
It's not throwing a CEL or anything when it's got the symptoms.
Anyone have any ideas? I was thinking possibly a bad coil or injector connection?
