check the timming belt it mighta jumped time or broke.

Remove inner panel carefully. find 2 black circle stickers and raise glass to access 2 screws holding glass. Door vent does not need to be removed.

It appears the car may not be entering tuneup mode. warm up until temp is normal, idle stays below 1000 rpm
2000 rpm for 2 minutes
rev engine 2-3K three times
idle for one minute
turn off
disconnect tps
start
rev 2-3K three times
adjust timing

This is a bad throttle position sensor
