Once i re-assamble motor an tryed to start engine i noticed small amount of smoke quickly come from throttle position sensor . At first glance the mecanisim seems fine thow has melted an possibly fryed an lost bits ? Has any one had similar problems or have any help or idear wat else could be ?

Depends on what motor you have 5S-FE engine, 7A-FE engine, etc... Most likely you will have to remove your timing cover and you will be able to access it by removing your rh fender apron seal. It will be down by the crankshaft pulley. On some models they attach the wiring to the drive belt adjusting bar. Here is a link for a sensor for the 2.2L motor.

hi there firing order is 1342 no 1 cylinder is located from timming cover

What motor do you have? 7A-FE (1.8L) or 5S-FE (2.2L)

check for vaacuum leaks, if thats not it then you need ot check the MAF sensor (its right by the air intake)

It sounds like you have a vacuum leak. Check all of the hoses coming off your intake manifold, and off of the engine.

You do not need a lift, but you may have to get under the car to disconnect the cables, depending on the engine you have. See instructions below from autozone.com. I also recommend you read my post at http://www.fixya.com/cars/r5973094-starter_replace . Please let me know if you have any questions.

REMOVAL & INSTALLATION See Figures 5, 6, 7 and 8

Fig. Fig. 5: The starter is located on the side of the transaxle as noted-5S-FE engine

Fig. Fig. 6: View of the starter and relay location-7A-FE engine

1. Disconnect the negative battery cable.
2. Remove the air cleaner assembly.
3. On the 5S-FE engine remove the battery if necessary.
4. On models equipped with cruise control, disconnect the cruise control actuator from the body bracket.
5. Disconnect the starter wiring.

Fig. Fig. 7: From under the vehicle, disconnect the starter wiring

1. Remove the nut, then disconnect the starter cable.
2. Remove the 2 starter bolts.
3. Remove the oxygen sensor wiring harness from the engine wire brackets and starter. Extract the starter from the engine.

Fig. Fig. 8: Once the mounting bolts are removed, the starter can be removed from the vehicle


To install:

1. Attach the starter and oxygen sensor wiring and brackets. tighten the two bolts to 29 ft. lbs. (39 Nm).
2. Attach the starter cable and tighten the nut. Attach all other starter wiring.
3. On cruise control models, install the actuator with the 3 bolts, then connect the wiring.
4. If removed, install the battery. Face the arrow mark on the hold-down clamp forward.
5. Install the air cleaner.
6. Connect the negative battery cable.
7. Check that the engine starts.
8. Reset any electrical components such as the radio and clock.

Try the Cold start Injector it is in the center of the air intake manifold facing you. you cant miss it its on the face of the manifold and has a wire and 2 screws with a hose with a bolt through the center with a metal band around the bolt

with the timing belt on the vehicle install the botton piece of the timing cover with crank pulley. line up the notch on the crank pulley with 0 on the timing cover for top dead center on the crank. then there is a small sight hole in the spokes on the camshaft timing gear. with the belt off the timing gear line up that sight hole with a notch behind the gear on the cylinder head. you will only be able to see the notch through the sight hole with a mirror. once these are lined up slide the belt back on the timing gear and recheck afterward. this the procedure for all 5s-fe motors

Your catalytic converter needs to be replaced. It's becoming clogged, and preventing your exhaust from escaping properly.

thermostat faulty, leads to motor overheating result blown head gasket.Is there water comn out of exhaust, Is oil discoloured on dipstik?
