Hello, my name is***** it act like you have a rpm limiter such as not want to go above 2000-3000 rpm? Thanks.
Does transmission seem to be stuck in 1st gear? Is check engine light on?
Ok, I'm going to open question back up. Problem definitely seems transmission related but I cannot say specifically what. Someone else will reply when they can help, thanks.
hello, let me see if I can be of some help. Even though the check engine light isnt on, have you run a diagnostic check for codes with a scan tool? Since the motor was just replaced there may be an issue with one of the electronic control systems that can set a fault but not turn the warning light on or at least yet. Did you try dropping the exhaust system to see if the exhaust has a restricted catalytic convertor since the last engine failed? You didnt mention what type of blown engine failure, overheated,threw a rod bearing,etc.
Ok so you have new catalytic convertors and a lack ofpower on acceleration, is the fuel pressure low when the concern occurs. No other codes now?
Ok so exhaust should be free flowingno problem,it runs at idle fine but looses power under a load while driving . Is this a SOHC engine and did you put in a used engine? and No oter codes are stored now, it passes a key onengine off and key on engine running test?
Ok good. Long as fuel pressure is solid it could be due to an engine misfire, clogged fuel injector, something of that nature. Long as there are no transmission issues. An injector flow test should be done and take a look at mode 6 data if you can with a scan tool, this will tell you if you have a small misfire that isnt strong enough to trip a check engine light diagnostic code.
Very good. only other thing would be an issue with the crank psoition sensor if its loosing signal, or dirty mass air flow sensor. but that should either trip a code or show an out of range sensor when the concern occurs.
Its possible but it would tend to stall the engine and should set a code if its slipping or locked up when it shouldnt be.
Very good. let me know what you find.
