Hey People.
I have been lurking as a guest in this forum for quite a long time and have benefited A LOT from all you experienced 2ZZ owners.
But I now have encountered a problem that is not available on the forums or anywhere I look.
FIRST:
I will provide as much info as you need I always see posts with half information and it bugs you guys. I will include as much as i know here but if somethings missing I apologize. Just ask and i will give more info.
I am not new to cars, Not claiming to be a guru but I'm half a mechanic. I am an Engineer so I love this stuff and do it with pleasure.
The Problem:
IN SHORT WORDS I have lift once or twice in gear meaning I punch the gas in second gear, revs climb from 3k to 6200, Hits lift nicely, climbs to 7500+ ( i dont hit the limiter as I don't like to) and i shift, go a little more, then decelerate slowly in gear, go again from second and works good. And then usually the third time lift is completely gone as if the car is in neutral or not warmed up, bounces from the limiter at 6600rpm no matter how many times i try. And it starts working again if i switch the ignition off and then on and every thing is magically fine again and then it repeats everything i said before.
In a tiny more detailed fashion It has been a few days since my lift is acting weird. I hit lift and it works well 2 or 3 times (at max), and then boom. Its gone (Bouncing at 6600RPM the next time I go).
I come back clean the MAF sensor, the intake and everything else I see, (The temp was normal no signs of over heating)
I try tomorrow and the lift is back. and after 2 pulls (Meaning 2nd gear Lift achieved then 3rd gear Lift achieved), and when i repeat lift is gone. Again.
I park after a few mins turn the car off for hardly a minute, Come back Start the car set off again and just to check I try to hit Lift, and lift is back again until it goes away. ( That is how i know the problem is temporarily fixed when i turn the IGN off and on )
the problem is not concerned with how ling i drive i can drive for 200 miles and suddenly punch it lift would be fine for 2 times but would go away when i go into it again. and it still happens when ive just warmed the car up and set off when at operating temp.
Information:
1: I recently changed my Lift Bolts 1800 miles ago. They were not broken just mildly scraped.
2: Coolant is full.
3: Temperature is normal when the lift goes away, (i.e fully warmed up. I am not daft to rev it cold)
4: Lift works strong when it does come on, and is not weak. Goes to 7900 I believe my tachometer wont go higher.
5: Connections to the OCV are fine,
6: OCV filter was cleaned 3728 miles ago,
7: The engine sounds very healthy, No mechanical Issues apart from my crappy SRI Piping, sometimes goes loose and then the idle goes rough until i seal it again, and yes lift goes away even when it is sealed tightly i triple checked before and after the problem.
8: Engine oil is 3700 miles old 5w-30 Liqui Moly fully synthetic a tiny bit less from 5 liters
9: Engine Itself is 3700 miles old. (when i put it in it but looks like might be run for 10k miles before i put it from its condition which in my eyes is superb. Not bronze from mobil 1 either.)
10: I take care of my engine and the car like its my newly wedded wife.
Please can someone help me? its annoying and has me scared now i cant afford another engine right now. its fine if i hit lift once or twice but then goes away.
SORRY FOR THE LONG POST
