Well its a 1987 Stock SR5 and one day i went around a corner, and when i came out of it. It just started to die. I had to upshift it and it barely stay'ed alive. Well i gave it some gas and cleaned the carb, and changed the fuel filter. And now it ran great for 1 minute. Then now, when i give it gas (1k-3k) it seems very sluggish and wants to die, and jerks like crazy. Now im lost. Please some help would be nice.
