:{ I need you help, 89, auto, 2x4, 140k, new lift pump,injectors new stock,K&n box mod. valves adjusted. clean filters. The problem, when the weather starts to warm up the engine stalls at stops or when changing from reverse to drive. The a/c also pulls engine rpm down to stall. Old blue runs fine in cool or cold weather. No guages yet they are on order, and she needs paint real bad, But I still love her and want to get her fixed. I have another 93 and a 2002 all are great but the first gens are just classic tough I also like the heavy metal I can lean on her and she doesn,t dent or bend. Thanks for your help, I have fears of a worn out injection pump? Ken.
