Okay I recently regrounded everthing on my car to fix a 3800 Hesitation problem . I have tested the TPS it works fine . Well the car was running great for a few days then all the sudden bam back to running like crap again bogging out and all the stuff . If I slightly press on the pedal the car will gradually go past 3800 and all that just fine but . If I floor it the car instantly bogs out and will jolt in and out like if you were to stomp on the pedal continously . What can cause that to happen my actuators work fine even though id like to replace them just because . Also I am wondering if my boost sensor is bad maybe . 5TH/6TH ports are fine also . I have a new fuel filter and Fuel pressure regulator on it . I have an K&N air intake kit other than that right there the rest of the car is stock 86 N/A . What can cause this other than the normal stuff .I have looked at several hestiation threads and not many of them were helpful but I dont think this is anything to do with the ECU or grounding or TPS . I have been trying to solve this problem for like 3 weeks now . Any suggestions from the experts would be helpfull
