Well it all started today, after i installed my new ITR radiator and a new fan ( have no idea if its related or not) but after this instal my car would sometimes bog when you dont give it alot of acceleration, and it happens only below 3-4k rev range, it would keep doing for like 1-3 mins and then go away and go like it always does, when it begins doing it, if you give it alot of throttle it'll just bog a second and then would go normally fast, but when you switch to another gear and dont throttle it, itll just bog again. Anyone have any idea what is causing this problem ? As i said it happend when i installed my radiator(ITR) and a fan(CRX), actually a guy did that for me, and the only problem there was during the instal is that my previous fan blew out the fuse(10A), and we had to put a new one (30A), also right after installing the radiator i let the car run for like 30 mins at his garage, and the engine light came up, which happend again after like 2 hours of driving, Oh, and he also had to unscrew the exhaust manifold, right where it connects to the downpipe, just so you know the whole story..

 

Maybe it is your spark plugs, I had similar problem with my b16 It would only bog at low RPM and then it would stop as I would give it more gas, Check that for sure, that could also be why the engine light is on, it may be missfiring.

hope that helps.

 

Ok, so the matter has got worse, hat day i stopped at friends house for a couple of mins, and told my friend about that bogging problem, being a real friend, he wanted to check whats wrong with the car and started by pulling the cables that go into distributor from spark plugs one by one, they were all firing but when he pulled the last cable out( previous ones were put in right after he pulled em out and checked em), the car just stalled; after trying to start for awhile, it almost strarted and the white smoke would come out of the air filter, and then it died again, wouldnt start since then, and by checking the distributor , we figured that its just not giving any spark at all . Its giving the error code 43 ( oxygen sensor). We tried to take the distributor rotor arm to replace it and check for the ignition control module, but the rotor arm seems to be stuck in there, which is sposed to just slide off ? so we could do nothing about it, and replaced the main relay for a new one, which didnt solve the problem.
If anyone knows what it is, or had similar problem, please let me know

 

well maybe when he unbolted the header he unscrewed the o2 sensor that may b why u have the check engine light i dunno just a suggestion.

 

Please guys, say whatever ideas you got about it, cause im absolutely stuck at the moment
