ive searched in the forums and can't find anything specific to my problem. i have a 90 crx dx w/ a 94 b18b1 in it and i just test-drove it around the shop and it cuts out at wide open throttle. it feels like you are hitting a brick wall but anything less than wide open throttle and it is hauling *****. can anyone give me an suggestions on what it could be? the car has been sitting for a while so tomorrow we are going to drain the old gas and put in new gas
i was also thinking that the stock exhaust was too small for the car and was building alot of backpressure. what do you guys think? should i run open header until i get a bigger exhaust piping


suggestions please !!!

 

tps sensor

 

Sounds like the tps sensor wires were never reversed. Does it idle rough and cough up tons of black smoke? Or you got mixed up like one of my friend's did and hooked the plug for the map sensor into the tps and the tps plug into the map. Even more fucked up because it won't toss a code like that either...they both read the 5 volt range.

 

for future reference: the shop forgot to switch the two outer tps wires around. I went ahead and did it and it is running great.
