harobikes5690 · 07-25-2008, 07:31 PM

got my motor back in my car and it starts and i can drive it. it idles around 1200 rpms so i cecked the timing. i made sure i conectted the te1 and e1. i got the timing set to around 15 but if i go any lower the car dies whats wrong there?

i also have two other problems. in the morning when i start my car and after it sits for a few hours it stays at 1200 rpms for a few seconds then the rpms drops and it dies. i have to hold the gas pedal down at 1200 rpms untill it gets warm that way it doesnt die.

and then the other problem is it like wont let me rev past 5000 rpms when i try to it'll just die.

i can use any help i can get i've had alot of problems with this car.

check if timing belt alighment is wright.

harobikes5690 · 07-25-2008, 07:51 PM

what do you mean by that like the bottom end timing

Luni · 07-25-2008, 08:32 PM

The camshaft vs the crankshalft timing marks. Crankshaft should be set to 0 on the timing mark, and camshaft should be lined up via horizon marks, and the divot mark on the cam itself (have to take the valve cover off to see that mark). Also the dowel pin faces DOWN.

ok so i know how to get the crank lined up to zero. and one the cam you have the little pin thing on the end that the cam gear is on. is that the dowel pin? if so that needs to be facing down?

Luni · 07-27-2008, 02:53 AM

Yeah, it faces down, then in the head where the cam is theres an indicator mark thats like a V and a little mark that goes in the middle of the V. So the dowel faces down, then the mark should be somewhere around the middle of the V indicator.

If I had pictures id show you. But its something you SHOULD be able to see if you pull the valve cover off. Its easy to check mechanical time on a 5S even in the car. Just set the number 1 piston to TDC by lining it to 0 on the crank with the valve cover off. Dowel should be down, and the mark on the cam (the cam with the sproket) should line up.

Thats good info! I had to put a new engine in my MR2 and replaced the water pump and oil pump. Good I didn't move the cam or crank because once I got it back in the car it was pretty close. I just had to move the crank 1 or 2 teeth on the timing belt. then adjusted the distributor.

harobikes5690 · 07-27-2008, 05:14 PM

got the timing right. it was set at 10 and ran fine. i'm driving done the road at like 3 grand in 2nd gear and it starts backfiring and then dies. all it does is sit there and just turn over. what happened what do i do now

mr2magic · 07-28-2008, 04:01 AM

Does the dizzy rotor turn when you turn the motor over?

harobikes5690 · 07-28-2008, 12:05 PM

yea. i bought a new coil today hoping thats all the it is.

harobikes5690 · 07-28-2008, 12:39 PM

got the new coil in and it started right up. what can make a coil go bad cause this is the 3rd one ive had now

Luni · 07-28-2008, 02:52 PM

Dunno. When was the last time you changed dizzy cap, rotor, plugs, wires, etc?

harobikes5690 · 07-28-2008, 03:03 PM

change the cap and rotor after the rebuild and the plugs and wires were changed befor the rebuild which was less then 2 months ago
