Power Loss at 4400 RPM : 1.6 TS CF2
Hi, hope someone can advise on this as I'm lost now.
Car :156, 2001, 1.6 Twin Spark (CF2)
Problem : No power after 4400RPM under load as if hitting a rev limiter, but revs high without load
History : Intermitent power loss with engine warning light, became permenent. Failed component fault code for lambda sensor bank 2 (Pre Cat). Replaced lambda sensor (very slight improvement for a brief time then same as before). Cleaned MAF (no change). Replaced MAF (no change). Reset ECU (more responsive at low revs but still hits the wall at 4400)
Would be very grateful for any ideas.
