#40 of 49 Unstable Temperature Mitsubishi Eclipse 96 Turbo 4g63 engine by miteclipse96 May 28, 2009 (12:11 am)
I bought this eclipse to one of this magician guy here In UAE, it is a 96 mitsu eclipse DOHC Turbo with 4g63 engine 1st Gen. tried to put it back on the street, but the temperature was unstable, when I hit the accelirator from 100KM/H up to 130KM/H, temp guage start to move from the mid point to 3/4 of the guage, slowdown the car to 90KM/H it will go back to mid point, replaced the radiator into 3 rose Brass type, its the same, until one day the engine seised.   I bought Japan surplus engine 4g63 DOHC Turbo 2nd GEN, and replaced the following;      = water pump, timing belt, tensioner, thermostat, with NEW one, and a surplus original radiator for eclipse, put it back on the street, I've got exactly the same problem with the 1st Gen engine regarding temperature. trouble shoot again and replaced the following; coolant sensor, sending unit or guage sensor, with NEW one, swap the dashboard guage with another eclipse, check the working condition of the two electric fan, when the car is in idling position and reach a certain temperature, radiator fan will activate on low speed, after a certain temparature again, radiator fan will be in high speed togethwer with AC fan. Test drive again without a thermostat, still the same problem...........please help   Another problem, car is in idling position 800 RPM, turn AC ON, idling goes down to 400RPM, replaced the IAC, and re learn the computer for the idling by pressing the accelerator to 800RPM with AC OFF for about 5 minutes, it doesn't work.   I will really appreciate what ever help that you can extend to me, I've done all the basic things that I've learn about cars, but I consider my limitation, I can say that, it is really a nice fault, please helpppppppppp.   Thank you,   miteclipse96

Replying to: killer_chiyo (Oct 14, 2008 4:58 pm) Hi, here in UAE, 1990 up to 1994 eclipse has a 4g63 DOHC turbo 1st generation engine, 1995 up to 1999 also a 4g63 DOHC turbo but they call it 2nd generation due some modification on the crankshaft sensor and camshaft sensor, now pay attention on the wiring of the alternator, crankshaft sensor, and camshaft sensor, I've got the wiring diagram of it, if you need just post a message and i'll post it, I hope you've got the same engine, just incase you dont know your engine, there is an aluminum plate in the firewall midlle top, near the battery. Thank you, miteclipse96 Replies to this message: bootlegman (Aug 17, 2009 3:51 pm)

My 2003 spyder won't idle smooth and misses when sitting in gear and sputter badly when pressing the gas. Sometimes the rpms rev up real high when trying to make it go. I have to use manual shifting and rev the rpms up just to get it to run smooth and go. Please help!
