car not reving ^ 3k/limp mode
Hi Guys
My mate has a rx7 p reg, and has just rebuilt it with a mate,
when first started after a rebuild the car was idling and boosting fine after about 25 mins when the car was hot the car just misfired under throttle and wouldnt go above 3000rpm as if its gone into limp mode, and when shut off it takes abit to get going again
When the car cools down abit and the ecu is reconnected it will fire up sound and boost all the way through the rev range, but give ten mins and it will just do the same, until last nite we couldnt get it to work properly at all so its just stuck in limp mode and will barely rev and it will pop and bang and misfire, weve checked the obvoius ect inlet leaks vacuum leaks and there isnt any,
any help would be appreciated
Thanks in advance

Wouldnt jt be in constant limp mode if the CAS is faulty, last nite we would start it 6 to 10 times and it would start up and rev fine and work until we switshed it off, then we would have to the same process again until it started off limp mode, but you can tell when it starts up properly because the coolent sensor takes longer to come on would this have much to do with it

in relation to your earlier problem with your mates rx7, i too have the same issue tho my rotary has not been rebuilt, i was just wondering if you have sorted out this issue and how you have solved if so.

If it was the leading coils that had gone the problem would be constant, but this will sometimes start on limp mode, then switch it of turn it back over and it will start up sweet and not go into limp mode until uve turned it off again
