I have an 84 Chevy Citation X-11, I pulled out the engine due to its Crankshaft snapped by previous owner. I yanked the wiring from the car I Dropped a 3800 series 1 N/A from a 92 Regal in it but to make things easier I used 3300 components on the engine from a 91 Ciera. Everything 3300 converted was the ignition module, F. Injectors, Crank Sensor, Reluctor plates behind Harmonic balancer, entire engine wiring harness including computer and wiring through out the whole car front to back. It has taken a good deal of effort to pull it off.. But now I face a problem I nor anyone *including dealership mechanics* can figure out. When I start the car is shakes..not bad but enough to feel thru the car, it will smooth out to a degree but when you hit the gas the car bogs down badly. Fuel pump is working fine with correct pressure at regulator, Spark plugs are carboned but not fouled. Ignition module tested and good.. Only thing I can think of is F.injectors they came from a junkyard Ideas? TY

Engine is a distributorless setup. Has 3 coil packs that sit on the ignition module.. but yes I am leaning more towards fuel injectors but I thought if I had a bad fuel injector there would be alot more problems than what I am having.. starts right up with no problem, it just shakes and bogs down badly. Also can anyone lend some insight on how to check if a fuel injector is bad?

This is a good one. I'd check to make sure all the sensors are working properly and getting the information back to the on board computer. It sounds like when you hit the throttle, there is no signal telling the computer to speed things up. It acts like the throttle position sensor might be malfunctioning or just not working at all. Some deaership mechanics are very good, but many don't know how to handle customized situations like yours. Good luck.

Im a ford man, with that being mentioned it is tough for me to inform the reality however right here it's. Go with a Chevy/GM LS1 350. If you've gotten a few additional coins throw a rapid or perhaps a dual rapid mounted on it. Great vigor for the money and alot of persons have already performed the change so discovering the expertise and tech aid must be effortless Good Luck.

Make sure your plug wires are on correctly. Sounds like it could be a bad dist. rotor or cap. Any increased load (revving) increases the voltage requirement at the plugs and the spark seeks the easiest way to ground, through a crack or moisture. Also make sure you use good quality cap and rotor. I have seen cheap new aftermarket parts that were bad right out of the box.

ok i think it might be your fuel injectors if not check the coil or your cap and rotor

I WOULD SAY THAT THE FUEL INJECTORS ARE BAD.
