Hello, I have a 3yr old re-built engine and have been running great up to a week ago it started to run very rough, to the point that while stopped at a light or turning slow with out having gas peddle accelerated the truck will turn off. It turns right back on, but also in one big notewhile in park just in idle it is missing very bad to the point that is shuts off. I had my son stay in the truck to keep the motor idling at a higher RPM and while I am looking at TBI carburator fuel injectors, I see that gas sprays a perfect gas injection to carburator, but I found that the reason motor is running very rough and like no power is that I see gas coming out of injectors and it stops and goes. It is not a constantspray of gas, so I thought that it would be the fuel filter and replaced it. Still same issue, so a friend of mine that works on my vehicle checked the fuel pressure and fuel pump in good also. Keep in mind, this is not all the time. Motor runs perfect for a while and out of no where if starts with the rough idle. Might be a sensor! I am fustrated at not finding the fix.
have the same problem?
