Gold FFM C8RKH Posted December 27, 2020 Gold FFM Report Share Posted December 27, 2020 First question really needs to be why have you replaced three engines? Where they all faulty? Really? Second question would be does your garage really know what they are doing? Apologies I cannot be any better help than that but this is the first time I have heard of such issues regarding multiple engine swaps.

electro_boy Posted December 27, 2020 Report Share Posted December 27, 2020 Was the new engine new or reconditioned? Have the issues started as soon as new engine was installed or was out working fine for a bit and then stopped working? Have your garage absolutely ruled out electrical issues. There are a ton of new sensors and wiring to plug in and get correct in a modern engine. The info on the binnacle doesn’t make 100% sense. Eg engine is at ~2K rpm but all the shift lights are on. To me suggests something is not calibrated correctly or communicating correctly with the ECU. Im guessing you are using the factory ECU with the engine? Do the garage have access to the Lotus diagnostic software? or failing that get a standard OBD reader and see what error codes are being produced.

Khalidalsanea Posted December 27, 2020 Author Report Share Posted December 27, 2020 (edited) This video I uploaded from the technician from the dealer here in kuwait he recorded the video he was saying that my engine is working probably and having a rough idle when the car is on idle after the engine gets to the normal heat so after the cold start he says it might be from the throttle body on the maf sensor he says that he cleaned them both and still having rough idle and to change the throttle body it costs here in kuwait 1460 kd around 5k$!! For the throttle body only thats why im hating the car and the company as well so im looking for alternative parts so i can fix the car and sell it cleaned and installed Edited December 27, 2020 by Khalidalsanea Quote Link to comment Share on other sites More sharing options...

electro_boy Posted December 27, 2020 Report Share Posted December 27, 2020 Sounds like the mechanic doesn’t know what they are doing. Are they an official lotus garage? If not maybe consider taking your car to different place. The garage should be able to pull diagnostic information from the cars ECU showing the throttle pedal position, throttle body position, MAF readings etc and explain to you exactly why they are suspecting malfunctioning parts. At idle the throttle body should be pretty much closed, can they show you if this correct or not. Can they show you what the MAF readings are at idle and show how these values are different from the expected values? The throttle body position should move in correlation to the accelerator pedal. Can they show that the throttle body does not respond correctly to the accelerator pedal inputs. Can they show the ECU is sending the correct values to the throttle body? According to Deroure a new throttle body should cost about £1,200. Are the import duties in your country so high as to push the value to £3700 ($5K)? https://www.deroure.com/partinfo.asp?MAK=1&MDL=20&TBL=12712&SMA=0&SMO=0&ST=&SC=0&PBID=1089134 Quote Link to comment Share on other sites More sharing options...

Gold FFM C8RKH Posted December 27, 2020 Gold FFM Report Share Posted December 27, 2020 You shouldn't be hating the car you should be hating the technicians. Also, what's with the blue and red paint on the engine and supercharger? Sounds to me as though people have been messing with the engine of your car and not quite 100% competent. No way you should need 3 engines etc. Quote I came into this world screaming and covered in someone elses blood. I'll probably leave it in the same way.

ramjet Posted December 29, 2020 Report Share Posted December 29, 2020 As this engine is from a Toyota Camry and I have known a lot of people with those cars as well as many people on here would know of those cars as well, the requirement to change three engines just does not seem correct. MAF sensor and throttle body are things that they should have looked at first. Not after three engine changeouts. Wait to see what Bibs can find out from the factory in the New Year Khalid. Was the car running ok when you first bought it? 1 Quote All we know is that when they stop making this, we will be properly, properly sad.Jeremy Clarkson on the Esprit. Opinions are like armpits.
