thug252 Posted August 20, 2005 Share Posted August 20, 2005 When I bought the car it did not run. The motor was seized due to oil starvation After installing a Japanese engine in my 1992 lexus es300, and running the engine, raw fuel comes from the tailpipe. I then removed the motor and exchanged it for another motor which I installed in the car only to do the same thing. I do not know where to start. The engine in the car now is a japanese engine with a US intake manifold it runs but is missing and has fuel coming from the tailpipe. any help is appreciated.

Toysrme Posted August 21, 2005 Share Posted August 21, 2005 Sounds like you've got weak ignition in some cylinders. A 3vz-fe will run on 2 of 6. Stupid !Removed! OBD-I won't even throw a code. :\ Check the coil, dsitributor's rotor & cap, plugs & wires. On a side note: What's: The cam timing Ignition timing "VS" voltage comming from the air-flow meter (Yellow wire-blue stripe, or cut the top off & check the votlage on the flap arm) with the engine off & the key ON, & with the engine idling what is the voltage on VF1 & VF2 with the engine idling Fuel pressure @ idle Unplug the cold-start injector's electrical connector & see if it goes away Check injector duration (Digital multimeter's dwell function) How bad is the gas smell / fuel vapor. If the cat is bad, or you don't have one, it's going to be like that until the o2 sensors warm up & the engine enters closed loop mode.
