Lboogie Posted February 17, 2022 Share Posted February 17, 2022 Ive replaced my 1991 LS400 engine and had no issue until I put gas in as it sat for 18months , now there is a loss of power . Ive replaced the fuel filter and pump and dropped the tank and cleaned it with no change! Ive tried reading the codes both under the hood and the drivers seat! Can anyone help me with this issue Quote Link to comment Share on other sites More sharing options...
paulo57509 Posted February 18, 2022 Share Posted February 18, 2022 You replaced the engine; Why did you replace the engine? What condition was the replacement engine in? Just a salvage yard, used engine swap? Did you swap parts from the original engine to the replacement engine? Did you do anything to the replacement engine before/after the swap? Scanned for codes; were their any? Describe "loss of power". Is loss of power constant or intermittent? Have you checked your fuel pressure? 1 Quote Link to comment Share on other sites More sharing options...
