Timing on a Toyota Tercel with fuel injection 1993

If ur car runs fine b4 and now it has a problem after the timing belt r&r. Most likely u missed something. Did u use the toyota service manual or just some el cheapo book from a parts store. Sounds like u had the timing belt installed incorretly. Lets do this. Do a static compression and email me the reading. And I'll followup. If u have ur cam line up with wrong cam timing. Too much fuel b4 or after valves close. Of course ur O2 sensor seeing too much hydrocarbon or not approriate O2 content --> turn on the chk engine lite. Its doing its job. What & where on god green earth that a component code came on that make u think a component indicate it is defective. Hey man. Stop throwing parts at a problem. Understand the sys 1st and verify it is a bad component
