My RSI cuts out at 6000rpm and i need to find out the course. Normal is 8000rpm

HI ziptie12 Its a 4A-GE (20Valve Black Top) Not sure what you mean for which country. I am in South Africa

They did't sell that in the U.S. that's why , for that question. My info shows it's got 4 individual throttle bodies and 5-valve per cyl. set up with VVT-i , is that correct? IF so , is it still stock(original) or do you have any mods on it ? When you say 'cuts out' at 6K do you mean like it bogs down , or is it going into 'fuel cut' mode as if it's hit the red line already?..........Do you have a scanner that can monitor live data?

Well the only modification i made on the car was putting a free flow exhaust system. That was a few years ago though. When i say it cuts out its like im hitting the red line. When i excelerate slow then it goes beyond 6k.

Only thought I have so far , is cam/valve timing(VVT-i) and worn timing chain. Are you able to monitor it with a scanner while someone else is driving? OR if scanner is capable of recording a 'snapshot' of data while it's under the condition you describe............By the way ....Johannesburg? .........Long way from here in West Virginia!

I took it to a mechanic last night. He will put it on a scanner today to see if it picks up any errors. lol, yeah im actually in Johannesburg, South-Africa...

I'm used to Hondas' variable valve timing stuff , I don't know what software Toyota offered on a '98 Corolla over there. IF you can run a self test through the scanner of the VVT-I function or if it shows it on live data while driven , that may give clues. Keep me posted I'm curious.//////////////////////////////..................,,,,,,,,,,,,,,,,,,anything?...04/03/2014
