I just installed a 95 JDM H22 in my car, When putting on the timing belt the first time it was a tooth retarded. yesterday I fixed that and timing is perfect, but if I give it more than 15% throttle it bogs down and comes close to stalling. At idle it runs smooth, and with a little thottle it runs better than before. Does anyone have an Idea on this?

 

I would think the timing is still off. Did you make sure the #1 piston was at TDC when you replaced the timing belt? Did you make sure the pistons were in the same position each time you changed something?

 

Yes timing marks were right on, and tried adjusting some on cams and it got worse. Tell me what everyone thinks, I have the motor in a del sol. Would the h22a need more fuel than the stock del sol (d15a) fuel pump would give. I am going to upgrade anyway, will post if it helps. If any other ideas are out there let me know.

 

i would definately think so. Tell me everything you have going on with your car right now. Anything thast not OEM, tell me.

Did you put piston #1 at TDC when you were putting everything back together?

 

make sure you didnt mistake the TPS sensor for the Map sensor and vice versa.

TPS and MAP are the same connectors and will plug into each others position. The car will still idle perfectly but if you try and drive, the car will die.
