1987 Honda CRX running problem

All Honda 4 cylinder engines that I have worked on have a firing order of 1342. That is the firing order on your CRX. #1 is the cylinder closest to the timing belt.

I hope this helps, it all I could find.

Hope this help.

My main concern is that in 1990 Honda offered 2 engines...the D15B1 or the D16A6. I am going to assume that the engine in question is a D16A6, and the torque specs is; 47 ft/lbs for cylinder head bolts. When installing the bolts, dip them in CLEAN motor oil before inserting them into the block, and then tighten them as follows; there are 5 bolts in the front of the head, and 5 bolts in the rear. For the sake of explaination the front bolts are numbered from left to right...1,2,3,4,5 and the rear bolts are numbered from left to right...6,7,8,9,10. The correct tightening sequence for this arrangement would be; 3,8,2,9,4,7,5,6,1,10. I would recommend tightening the bolts to ~26 ft/lbs the first round, and then to 47 ft/lbs for the final round. Hope that this helps.

from the battery to the frame then to the Tranny

hope this helps!

I would suggest an ignition module. If it is a rough idle at startup I would check the throttle position sensor. You can check that by starting the car and unplugging the TPS. If the car runs differently then chances are it is working fine.

Forget about it with the money you will spend even if it is possible to swap, you could buy a newer car.

this is not the problem of fluid, this is a major problem of transmission. The transmission must be detached from the engine, which you cant do by yourself. the transmission can be repaired but i dont know mechanics in your do it. otherwise you have to replace the transmission.

it is on the left side of the engine under the intake tube
