Guys,

That problem i was talking about the other day never fixed, i just never drove it hard enough for it to come back.........

Here is the story the car does one big hesitation like its hitting the boost cut big time when i floor it but only in first gear! and it does it around 4,000 rpm every time, no other revs and no other gears..Although you car rev the car on light load all the way out in first gear.......Now this problem only occured after id gone to get the cat removed, it ran ok for about 15 minutes then started doing this so i put the old cat back on and its still doing it!

I just reset the ECU hoping that would fix it in case it were in limp mode but it hasnt!

Any ideas please guys, this is really pising me off! Can someone tell me all the hoses i should check or show me a picture of where they are becuase i dont know where any 'vacume' lines or the same are becuase i havnt had the car long and its my first rotary. Could the guy at the exhaust shop possibly wrecked anything by just removing a cat in the first place ?(even tho its back on the car now) Like that air pump hose wouldnt wreck anything would it? Just wierd that its at the same revs and in the same gear, no other gears are doing it! Help!

 

What's your fuel level? If it's low you could be sloshing the fuel away from the pickup in the tank and starving for fuel. G-loads in acceleration are highest in 1st gear.

 

Yeah i thought about the fuel thing, but ive got 1/4 of a tank of fuel, surely thats enough>? I a had a local rotary guy order me a new fuel filter for next week as well. But it deffinately sounds like some sort of starvation problem, im going to get new spark plugs put in as well.....Any other ideas? checked all turbo pipes etc and they all look to be fine......

 

Ok so definately seems to be a fuel starvation thing becuase when i dont have alot of fuel in the tank it will do it only up hill not down, however soethings not right when theres a 1/4 of a tank in there, surely the pickup isnt that bad that unless you have more than 1/4 tank you can flatten it up a hill? Could a clogged fuel filter be causing this? Any ideas please guys!

 

should of gotten in that fuel cover gb awhile back

 

Fuel cover GB? Eh? do u have something to add that might help?

 

The fuel cover is a baffle setup to keep the fuel pickup surrounded with fuel at high G-loads, mostly aimed at eliminating fuel starvation with low fuel while cornering. FD's are known for fuel starvation with less than 1/3 tank of fuel under high-G cornering, and, apparently, in your case, acceleration. It was offered as a group buy (don't remember the price) several months back.

 

yea i got one i think itand i dont worrie about turning or accelerating with low fuel but normally i fill up at the last quarter tank.

here is a pic of how it looks like https://www.rx7club.com/showthread.p...ht=surge+cover

and i cant seem to find the gb thread but this is closest i got https://www.rx7club.com/showthread.p...ht=surge+cover

 

man i dont remeber what i wanted to say in the first sentence that i messed up on "i think it"

 

The other thing is would a bad fuel filter be causing what ive described?

 

I don't think so. Clogged fuel filters usually show up at high sustained loads, i.e., in higher gears under high sustained boost. The symptom is a drop in fuel pressure.
