Right, I've bought a car with an early bluetop 4AGE.

It's an AE86 Sprinter Trueno GT Apex

(same model and colour as Initial D).

There's a big thread in off topic about it.

When I test drove it, it had a horrible flat spot at 3K which was really annoying as it's hard to avoid.

Also the engine felt a bit sluggigh

(but I do admit to testing a blacktop 20v Levin earlier which was stonking, shame about the rest of the car) through the rev range, though I wonder if being put off by the digital dash was a factor as it didn't seem that bad at higher rpms.

So when I go to pick the car up next week, I'm going to change the ignition components.

I noticed tha the engine was missing the spark plug cover and had later leads on it which are not the same as bluetop ones.

Also the guy admitted to not servicing it, since it landed in November 2010.

I've bought

(all from Toyota):
Dizzy cap
Rotor arm
OEM Spec platinum plugs
HT Leads

I'm thinking it's missing a bit all the way through the range.

Am not absolutely convinced that changing these items will sort it.

It might need a bit of a throttle body clean.

Obviously will check the timing too, but I'd reckon that a timing issue wouldn't cause a flat spot.

Any other thoughts on what it could be.

Only other thinking was a shagged TPS or it's well rich.
