In addition to 4Crawler's suggestion, clean your throttle linkage to start with. I don't think your CS injector would affect this. IIRC, your temp sensor affects the kickdown after warming up. Check your coolant level too; the 22RE's are rather persnickety about being topped off.

We also have an FSM for a '93 sticky'd in the early trucks section for your troubleshooting use. Be aware there's 3.0 info in it as well, so mind what you read.

Also for your year, for $10 you can download your FSM at www.techinfo.toyota.com; it's schweet. <img src="/forums/images/graemlins/kewl.gif" alt="" />
