Topic: 1990 cq troubles me!!

[mi-audiguy]

i purchased it for $700 about 3 months ago from a guy that told me it needed a head gasket. after tearing it down and doing the head gasket, timing belt, water pump, etc... i started the car and it did not run any different. it had a new rad. when i purchased it and i came to find all the cooling issues were from a faulty coolant cap!!! i never had a 20v before this one and it seems really sluggish to me. it starts to wake up at about 2700 rpm but still not impressing me. 0-60 feels like 8 or 9 seconds and there is a slight hesitation through the whole rpm band. so next i was thinking maybe it might be injectors so i was going to go with this kit- http://www.034motorsport.com/product...roducts_id=329 - not exactly sure what else the issue may be and i would like some insight from someone else that may have encountered this hesitation or am i just imagining this all and the cq is supposed to be so sluggish

have you done a tune up? just a fyi these cars are slow to begin with

the 034 injectors were a huge upgrade for my CQ and it did help with a slight hesitation.  Of course by the time I did them I had replaced just about everything else so it worked well for me.

in the process of doing the head gasket job i went through it all. water pump, complete head gasket set, timing belt, camshaft timing chain, plugs, wires, cap, rotor. drained and replaced all brake fluid, power steering fluid, coolant, i was trying to be thorough with it. coolant light comes on and temp does not read right though. oil pressure and temp gauge work fine... i will replace those sensors soon. when i had the motor apart the original factory cross hatching was still on the cylinder walls. i am considering going turbo with the 034 kit

but i want to make sure it is not something major before i proceed.

sounds like the motor internally is good to go for a turbo kit

ok fuel filter is now done... with no improvements to be seen yet so i started checking all the injectors and #1 and #3 are bad so i just put in the order to 034 for the injector upgrade and i will keep you all posted on how well it turns out!

I'm sure you'll love the change with the new kit.

hahaha funny how that works when you're only running on 2 of 'em!

glad u figured it out.

alright i took it for a test ride after work today and after it warmed up it started to run like crap again!!! i took it on 696 got it to 90 and it started sputtering. two thumbs up on the injector upgrade though! it is a nice set up. but now i have another symptom that i have to figure out. plz help if you have any ideas for me to start looking for this issue. thank you

[Castle]

have you check the distributor?  Plugs?  Wires?  I chased some issues on mine back in the day and Stefan showed me the trick of spraying water on the wires to see if they are sparking.

Glad you like the injectors....when you get the problem figured out you will find your car pulls better and runs smoother than it did the day it drove off the lot.

[mi-audiguy]

new plugs, wires, cap, and rotor... what sensor might be screwing up when the car warms up?

[ken]

Crank sensor?  In my experience they just die, but that controls spark, fuel, and timing.   Coolant temp sensor maybe?   There was a guy on Car Talk last week with a CQ that ran poorly before it was warm.  They suggested injectors or collant temp sensor.

this one runs like crap when it warms up.
