Hi there
I bought a 1.7 vct couple months ago, it’s not in mint condition on the exterior, but in terms of engine looks almost like new....but I came across a small problem and even my mechanic is trying to figure out was going wrong.
About 2weeks after buying the car e decided to do oil change, found out that the “recommended” was 5w30...after the oil exchange, I started to feel the car sluggish and struggling. Had no idea what oil previous owner used, so I took out the 5w30 and used 10w40, I’ve noticed the car was almost back to normal, was so sluggish, got new spark plugs and it looked like problem was solved.
Unfortunately when it reaches 3.5k(vct kicks in) it struggles to reach 4K....after 5k it’s like vct finally kicks in.
Got new speed sensor cuz the needle was wobbling from 0-60.
Tried out the MAF, unplugged and the engine was stuttering, cleaned and put it back in place.
Checked the lambda, unplugged, was working just fine, tried to take it for a spin and it seemed it was running out of gas, plugged it back.
My doubt is the O2 sensor....I unplugged and no lag in rev, everything was working perfectly, until it started struggling again around when vct kicks in, took sensor out and it was black, gonna get a new one and install.
My question and hopefully someone can explain exactly what’s wrong...could it be the solenoid? Or something else?
Also I’m trying to convert my puma into a FRP, as far as I know it’s gonna be the only one in Portugal, anyone knows where I can get the body kit, brakes and all that material, specially I want to boost up the engine but I want to make it right way, where can I get forged pistons(kit)?
Thank you for your patience
