Easiest way to do this is probably to list the symptoms I've got and go from there.
• Engine miss-fire at idle when cold
• Very easy to stall the engine when putting under load when cold, say reversing etc
• Car pulls and drives absolutely fine under power
• After a good drive when it's hot, the miss-fire returns at idle, slightly worsened
• when coasting or maintaining a speed, say 30, it feels like the engine is snatching every now and again
However, like I said, it pulls and drives fine, if you've got the throttle on, there's no hint of a miss-fire or anything, it really is spot on.
The only modifications from standard are a cone filter the previous owner fitted, which I'm removing next week for a standard airbox, and the car has a powerflex lower gearbox mount fitted.
I'm going along the usual lines of checking the throttle body out, I can't see any issues with the coil pack, it's just been serviced etc, however I also noticed the other day that after I'd left it for 2/3 days it cranked over more than normal before it started, as if it was low on compression.
I bought the car knowing it had a top end rebuild last year after the timing belt snapped, there's a receipt for all the work including 2 valves. I guess what I'm thinking now is that from the symptoms I've got, its sounding to me like there's potential for piston / bore damage to the block on one cylinder resulting in lower compression? Easiest way to check will be to do a compression test, so I'll try and get hold of a tester, but it's not using any oil, and I'd have thought it would do if there was bore / piston damage?
Argh etc? It drives fine, but the idle is starting to hack me off.
Suggestions before I take the engine out and kick it a bit?
