Hi there. I have a 2001 ram 1500 5.2 and i just replaced my intake manifold gasket. I took the proper steps and re-connected all the sensors and injectors, cap wires etc. The timing is spot on. My problem is when i start it i have to keep my foot on the gas for it to run but i can smell in the exhaust that there is tons of unburnt fuel. Ive double checked everything, it gets spark and has compression. Would it be a bad or dirty injector? Any suggestions? I need it done tomorrow. Any help i can get would be great! Thanks.
