Guest crunchy Posted March 17, 2004 Share Posted March 17, 2004 hi people ive just joined the forum, i have a 84 l20et skyline and for some reason it wont rev pass 4k and the only does it when going down a hill sometimes. ive done the pump and injectors and check all electrics. it starts fine and pull ok till 4k then it surges and stumbles and wont rev. airflow meter looks fine and is free to move, any ideas would be great. or it also has a custom ball bearing turbo on it that i build, cheers Quote Link to comment Share on other sites More sharing options...
Ben Posted March 18, 2004 Share Posted March 18, 2004 Hey Crunchy, Sounds like the TPS idle contact may be causing your problems. One thing to try: free-rev the engine up to 5000rpm, if that fails, disconnect the TPS & try again. Report back on your findings. Quote Link to comment Share on other sites More sharing options...
