Hello evereyone.
I post my problem here because I’ve search for weeks now and can’t figure what my problem is.
Lets start with the beginning of the story.
I had to rebuild my engine, I change it all and streetported it. I put everything back in place and start the engine. The engine start and keep stalling. Rookie mistake, I forgot to reset the PCm for the shaft sensor. It was better but still stall at idle, rough idle. Another rookie mistake was found, I inverted fuel injectors wires. Still no resolve the problem…
I know the PCM need some time to learn how to fuel the car so I decided to drive it around the block but it show me another problem, everytime I push the gas pedal it struggle for 1-2 sec and then it goes well (I’ll try to upload a video to show this soon), but everytime I get off my foot and put it back on the pedal, it will do that.
Driving it comes also with a lot of backfire. I check the plugs and they’re black, so it’s sure, the car run too rich!
I looked over vaccum leakage, found nothing, check the ignition (D585 coils) they’re good, I took my compression, 100km after the rebuild and I got 105-107PSI for all faces and front and rear, so not really great but not bad at all I guess!
So now I don’t know where to look up to find the problem.. For me it may be a sensor trouble, may be the MAF or the throttle body, I’m waiting for remplacement parts but I’m scared it won’t be that..
About my setup : D585 ignition coils and wires, NGK plugs. K&N air filter, and a full exhaust from toyosport (decat pipe). I don’t change those during the rebuild. I just add a oil pressure regulator during the rebuild.
If anyone have a clue for me to solve this problem, I’ll take it!
Thank you in advance and sorry for the bad English!
