First replace your fuel filter.Then give your entire throttle body a good cleaning. If no change, test your fuel pressure. You may have a bad fuel pressure regulator. Do you smell a strong fuel odor under the hood? You may have a leaky injector. Could be numerous things. Throttle position sensor could also be faulty. If the car had no issues prior to you doing the engine work, carefully inspect all of you vacuum hoses to make sure that they were all hooked back up properly. You may have overlooked something simple.

TimmyM, is your check engine light on? If so, have you had the error codes read? You have already replaced most of the usual suspect parts. Check these other possibilities: Vacuum leaks (especially the large intake hose that feeds the throttle body), clean the MAF sensor with MAF cleaner, check for exhaust leaks, (press hand over exhaust pipe and listen for any hiss noises), check fuel pressure with a gauge. Low pressure will cause a backfire. Post back with results.....good luck!
