Just pull a spark plug! It will tell you the mixture, timing, and if you have detonation. If it checks out good, then I would look at the TPS. Dave W

There is a cold start temperature sensor on the coolant neck that could be a problem. Verify that the cold start injector is getting an electrical signal. Dave W

Re: Kitsunami's 86 SR5 to GTS swap

As old as these 4AGE engines are, you would be lucky to get a good short block from a pick and pull. I would look at getting the crank turned [probably $90] that way you know you have a good bottom end. Do not but bearings until to get the crank back from the machine shop. Dave W

Re: Horn don't work help?

Use a test lamp and see if you have current going into the horn. If you do not see current at the horn check the fuse. If you do not see current, in either of these cases, you have a problem with a plug connection or a broken wire. Odds are pretty low that the horn actually stopped working. Dave W

You normanlly modify the piston Vs the head. You would not want to countersink the valves into the head which reduces flow. Typically those mild duration cams are not any problem.

Re: AE86 SR5 Rear End?

The SR5 rear axle is more the adequate for a stock 4AGE. The SR-5 axle [S series 6.38 ring gear] will have a 3.9 ratio or a 4.10 axle ratio. The axle is probably the 4.10 since the original car was an automatic. This ratio, actually better suits the power band of the 4AGE engine. Dave W
