[QUOTE="salstage2, post: 16171537, member: 187908"] How’s it going guys, I rarely post on here mostly I just lurk around and see the for sale posts but I have done just about everything in regards to this swap and I still have no solution. Let me get right into it. I recently swapped a 99 cobra engine into my 01 Roush. I COMPLETELY redid the block from top to bottom. Everything is new on the damn block. the major parts on the car are Stage 1 cams Bbk Tb jlt ram air Lightning maf Completely redone heads Mac Longtubes and prochamber So here’s my problem, The car will start but will die shortly afterwards. IF I hold the gas at startup and keep it around 1500rpm for about a minute the car will then hold on it’s own. If I drive the car sometimes it will die when coming to a stop and pushing in the clutch. It also breaks up on throttle when driving. I have a feeling that I’m 99% sure it’s tune related. Keep in mind 99% of the the parts on the swap are brand new so I doubt they’ll be faulty as well as I did Some things to make sure it wasn’t anything else TPS sensor was fine Brand new iac Brand new maf Brand new hoses New fuel pump NO vacuum leak No blown fuses Is there anything I’m missing to check or what would your guys’ opinions be? As mentioned I’m fairly certain it’s the tune but even then I put a tune that my brothers Mach 1 had that’s has the SAME mods my roush has except for the cams but it still has that problem. So I’m not sure if it can be anything else but the tune. I have the appt for the tune coming up soon but I wanted to see if there was anything else I should try before taking it to the dyno and what not. Any and all help will be appreciated thanks!
