Heys guys I need some help/advice on what to do with my car. Here's my issue and a little bio on the car...
year - 1988 7MGTE
engine - rebuilt (if you need spec let me know)
Miles - driven about 1100 mile so far
Background on issue....
My car developed a miss a while back but i felt i would fix it later due to having other issues to deal with. The car has always had a high idle (1100-1300rpm) due to my improper set up of the CPS. Car was zeroed out....just that when I installed the CPS I didn't leave myself alot of adjustment to back it down. Well today I decided to adjust the CPS and try to get it to spec idle range then properly time it. So when I got it setup and adjusted (idling around 750-850rpm) the 'miss' i felt at high idle was more pronounced that I could tell something is wrong. I started pulling the spark plugs from the coil pack to see if i could find the issue. Idle changed, for the worse, on every pull except No.1 cylinder.....no change....uhh ohh! I then pulled the wire from the spark plug and it was firing to the spark plug. I swapped spark plugs with number six to veriy it wasn't the spark plug. Same issue same cylinder so spark plug is ok.
So now I'm asking for help on what to do next.
Things I've done or planning to do. Would appreciate if anyone thinks i'm on the right tack or other suggestions.
1) removed spark plug to find and oily 'gunk' on cylinder. Used a screwdriver to lightly remove some off the top.
2) Will check resistance on the injector
3) Will use the online TRSM to check at ECU and resistor
Also on another note. If I done happen to get a fire in No.1 cylinder would the oily debris the cylinder be harmful? I really don't want to remove the head but i'll wait to hear what any of you have to say. It's late and i'll try and remember to take a picture of the 'gunk' in the morning.
